This paper presents the design of a fully integrated pulse generator which allows BPSK modulation to be implemented. This emitter is based on the response filter architecture and has been integrated in a 130nm CMOS technology with a 1.2V supply voltage on a silicon area of 2.88mm². The bandwidth at -10dB is about 1.8GHz around 3.52GHz. The output dynamic voltage is equal to 1.72V peak to peak on a 100Ω differential load which gives an energy of 1.93pJ for the twice bipolar generated pulses and demonstrates the pulse generator capability to be used for bipolar modulations.

This paper presents a low power Impulse-Radio Ultra-WideBand (IR-UWB) receiver for low range and low data rates applications. The receiver adopts a non coherent detection with duty cycling that allows very low power consumption. The receiver operates in the high band of the UWB frequency band. It has been designed for the 7.2-8.5GHz bandwidth and covers channels 8, 9, 10, and 11 of the IEEE 802.15.4a standard. The receiver has been implemented in 130nm standard CMOS process and occupies an area of 1.5mm 2 . Post-layout simulations of the fully differential Low Noise Amplifier (LNA) including parasitic effects of the package show 40 dB voltage gain and 4 dB noise figure. The LNA turn on time is less than 3 ns. When synchronized and duty cycled with an analog Clock and Data Recovery (CDR) with 23ns peak to peak jitter the receiver consumes 1.95mW at 1Mbps data rate.

This work presents a novel fast switching low power low noise amplifier (LNA) for 6-10 GHz ultra wide band applications using 0.13µm CMOS process from STMicroelectronics. The LNA operates at 1.2V. It achieves a high differential voltage gain about 46 dB with 4.4dB noise figure and a power consumption of 24mW. Fast on and off power switching is achieved by using differential amplifiers with DC coupled eliminating the use of large capacitors that leads to long charging time constants. The output voltage is settled in 1.5 ns when the LNA is switched on and off. The circuit consumes only 32.4 µW of dc power when duty-cycled@100kbps allowing reducing the power consumption.
