“…As delay cell are highly sensitive to PVT variations, the use of voltage controlled delay line allows the compensation of this variations. Two edge (V j and V k ; j,K ϵ [0.7]) are combined to produce complementary baseband pulses (Vc-i-n and Vc-i-p, i ϵ [1][2][3][4]) to control the transmission gate of different current cells (Fig. 8a).…”

This paper describes an on-off ring oscillatorbased multiband ultra-wideband transmitter for vital sign monitoring applications. A thorough analysis of the pulse generation is provided followed by a description of the oscillator, the mixer, and the AB-class power amplifier. Designed in a 0.18-μm CMOS, the transmitter works in the UWB lower band of 3-5 GHz and consumes a low power of 7.8 mW at 50 MHz pulse repetition frequency, under 1.8-V power supply. The transmitter delivers a differential output swing of 0.64 V under 100-Ω load with the highest power efficiency of 37.6 pJ.

<p class="lead">The objective of this research was to design a basic 2.4 GHz heterodyne receiver for healthcare on a 130um CMOS process. The ultimate goal for the wireless industry is to minimize the trade-offs between performance and cost, and between performance and low power consumption design. In the first part, a low noise amplifier (LNA), which is commonly used as the first stage of a receiver, is introduced and simulated. LNA performance greatly affects the overall receiver performance. The LNA was designed at the 2.4 GHz ISM band, using the cascode with an inductive degeneration topology. The second part of this thesis presents a low power 2.4 GHz down conversion Gilbert Cell mixer. In the third part, a high-performance LC-tank CMOS VCO was designed at 2.4 GHz. The design uses using PMOS cross-coupled topology with the varactor for wider tuning range topology. In the first part, a low noise amplifier (LNA) design reaches the NF of 2 dB, has a power consumption of 2.2 mW, and has a gain of 20dB. The second part of this proposal presents a low power 2.4 GHz down conversion Gilbert Cell mixer. The obtained result shows a conversion gain of 14.6 dB and power consumption of 8.2 mW at a 1.3V supply voltage. In the third part, a high-performance LC-tank CMOS VCO was designed at 2.4 GHz. The final simulation of the phase noise is-128 dBc/Hz, and the tuning range is 2.3 GHz-2.5 GHz while the total power consumption is 3.25 mW.<strong> </strong>The performance of the receiver meets the specification requirements of the desired standard.</p>

The objective of this research was to design a 2.4 GHz class AB Power Amplifier (PA), with 0.18um Semiconductor Manufacturing International Corporation (SMIC) CMOS technology by using Cadence software, for health care applications. The ultimate goal for such application is to minimize the trade-offs between performance and cost, and between performance and low power consumption design. This paper introduces the design of a 2.4GHz class AB power amplifier which consists of two stage amplifiers. This power amplifier can transmit 10dBm output power to a 50Ω load. The power added efficiency is 7.5% at 1dB compression point and the power gain is 10dB, the total power consumption is 0.135W. The performance of the power amplifier meets the specification requirements of the desired.
