“…For each differential squarer, the left transistor pair (or ) will generate both a squared term and a DC term while the right transistor pair (or ) will produce an identical DC term. Using the ideal square-law characteristic equation of MOS transistor in the saturation region , the following equation can be derived: (8) where represents the current flowing through transistor , is the transistor device parameter, is the gate-to-source overdrive and is the differential input signal to the squarer. Similar result can be obtained for the other squarer with differential input signal .…”

“…15.4a compliant devices, is the ideal candidate technology for efficient power management, location and ranging capability in sensor networks due to its sub-nanoseconds pulse transmission and potential of achieving ultra low average power at low data rates [4], [5]. However, conventional simple non-coherent UWB IR transceiver [6]- [8] suffers from severe signal loss due to the squarer, and usually requires extensive subsequent post-amplification stages and integrator that cost both area and power.…”

Non-coherent ultra-wideband (UWB) transceiver employing energy detector suffers from degradation in output SNR due to the squarer. A burst mode super-regenerative UWB transceiver which can recover the received signal to rail-to-rail with relatively fewer post-amplification stages is proposed. Unlike other super-regenerative receiver architectures that use oscillator, the proposed architecture employs a positive feedback loop to achieve the super-regeneration of received signal and thus eliminates the need for external resonator or quench signal. The transceiver is suitable for low data rate sensor networks application covering spectrum of 3-5 GHz. Manufactured in CMOS 0.18-technology, the transceiver occupies an area of 2.2 mm 2 mm. By exploiting the duty cycle and the transceiver on-time through the burst mode operation for a given data rate of 1 Mbps, it can achieve transmitter energy efficiency of 0.671 nJ/bit and receiver energy efficiency of 3.54 nJ/bit.

Since UWB system uses a wide frequency range from 3.1GHz to 5.1GHz, package parasitic effects have been a hot issue which affects system malfunction. To prevent such malfunction, SiP technology is adjusted considering not only a circuit performance but various design issues in a package from viewpoints of signal integrity and power integrity. Furthermore, UWB band-pass filter is embedded into a package to reduce a complexity of transmitter circuit and the power consumption. Designed UWB SiP performance is verified by the measurement in time domain.

Non-coherent UWB receivers are often implemented using energy detection architectures which are very sensitive to noise in the channel and interference. Therefore, the receiver bandwidth plays an important role since the total noise and interference energy is proportional to this bandwidth. This work provides analytical expressions to find the optimal receiver bandwidth and quantifying the effect on the bit-error-rate (BER) due to channel noise and adjacent-channel interference (ACI). A reduction in receiver bandwidth beyond the optimal point is shown to have minimal impact on BER performance when ACI is negligible.
