“…The measured group delay (GD) that is shown in Figure is less than 0.1 ns with variation of ±40 ps for the RF input band that spans from 1 to 11 GHz. The figure‐of‐merit (FOM) to evaluate the proposed UWB LNA is given by :

FOM true[\frac{GHz}{mW} true] = \frac{S_{21} [Mag] \cdot BW [GHz]}{(NF - 1) [Mag] \cdot P_{DC} [mW]}

where S 21 (power gain) and NF are represented in magnitude, BW is represented in gigahertz (GHz), and power ( P DC ) is represented in milliwatts (mW). Table shows the performance summary of the proposed LNA in comparison with recently published CMOS LNAs.…”

A high‐gain, low‐power, and low‐noise amplifier (LNA) is designed in UMC 65 nm radio frequency (RF)‐CMOS technology for operation over the 1 to 11 GHz RF band. This LNA design is based on an m‐derived inductive peaking circuit with a shunt feedback inverter. The m‐derived inductive peaking circuit is placed between two shunt feedback inverters. Further, a split inductor topology is introduced in the circuit. The procedure for the integrating of an m‐derived inductive peaking circuit in LNA is explained in detail. The proposed circuit achieves more than 14 dB of power gain over an ultra‐wideband of 1 to 11 GHz. The measurement of the proposed LNA achieves a minimum of 2.5 dB of noise figure, and more than −8 dBm of third‐order input intercept point, while consuming 11.3 mW of power. © 2017 Wiley Periodicals, Inc.

“…However, the use of the feedback resistor inevitably deteriorates the amplifier's noise. The LNA proposed in [102] combines the complementary topology with asymmetrical inductive source degeneration. By omitting the use of large inductors and a feedback resistor, better noise performance can be expected.…”

Ultra-wideband (UWB) has emerged as a very promising technology for short-range communication systems. The ultrashort duration of UWB waveforms gives rise to the potential ability to provide high-precision ranging and localization. Accurate distance measurements between sensor nodes used for localization in wireless sensor networks (WSNs) are very attractive for advanced wireless health-care applications. Over the years, several localization methods like received signal strength intensity (RSSI), angle of arrival (AoA) and time based approaches such as time-of-arrival (ToA) and time-difference-of-arrival (TDoA) exist for distance measurement between sensor nodes. The dominant RSSI is simply estimating the node distance by measuring the strength of the received signal. However, precision is too low with this method. ToA ranging approach is simple but require synchronization to give good precision. Clock synchronization between the transceivers is limiting the accuracy of the ToA estimation and hence increases the design challenges of the UWB ranging system. To our best knowledge no high-precision localization solution suitable for in-body tracking is reported. Impulse radio ultra-wideband (IR-UWB) has been an interesting area of research for lowpower short-range applications. Several studies indicate time-of-flight (ToF) measurements combined with the good temporal resolution of IR-UWB can give good precision. Typical distances between sensor nodes are in the order of ten meters that requires distance measurement is approximately one centimeter. Since radio waves propagate with approximately the speed of light, the time differences of less than 30 ps are required. With traditional clock driven circuit solutions, we need a clock rate of more than 30 GHz, which is not easy in standard technology. Using the new circuit solutions that are still in digital value but continuous in time (Continuous-Time Binary Value-CTBV), it is possible to find effective solutions for precise distance measurement in combination with communication, all are integrated on a single chip. The main goal of this thesis is to develop an IR-UWB receiver front-end covering the frequency band of 3-5 GHz for the CTBV ranging system. The front-end consists of an antenna, a low noise amplifier, a band-pass filter, a downconversion quadrature mixer, a low-pass filter, a differential-to-single-ended converter and a continuous-time quantizer. These building blocks are assembled with other circuit elements of a functional impulse-based radio chip that is demonstrated at short distances. To reduce complexity and to minimize the power consumption, the proposed IR-UWB receiver front-end has been implemented as an energy threshold detector. The quantizer with tunable threshold acts as a single-bit ADC is implemented as a demodulation function. By avoiding using external components as well as high frequency sampling clock, the IR-UWB receiver front-end consumes less power and fully integrated is possible. The proposed IR-UWB receiver front-end is suitable for...

This article proposes a new wideband active power splitter design where the gain cells along the input transmission line are arranged in interleaf rather than the conventional parallel style, thus the circuit's high-frequency performance can be greatly improved. Both theoretical analysis and circuit simulation have been carried out; as a demonstration, parallel and interleaf active power splitters are designed using 0.1 μm GaAs pseudo-morphic heterostructure field effect transistors (GaAs pHEMT) process and measured on-wafer. The results clearly indicate the superiority of the interleaf topology. A 40 GHz interleaf active power splitter in 90 nm complementary metal-oxide-semiconductor (CMOS) is then presented where the magnitude and phase imbalance between the two output ports are 0.15 dB and 2.6° at 20 GHz, and 0.16 dB and 14° at 40 GHz. The output-port isolation is better than 30 dB across the whole frequency range.
