Abstract :
This paper presents a low-power wideband LNA for the Super-Regenerative IR-UWB receiver. To meet the LNA figures of merit, which are the wideband gain flatness, low power and low noise figure, we have proposed an improved input matching network, combined with the current-reuse technique and the power-constrained simultaneous noise and input matching (PCSNIM). Designed with CMOS 0.18 μm technology, this 3-5 GHz LNA demonstrates the power-gain of 11.8dB with only ±0.4dB variation, a minimum NF of 3.5 dB and an input impedance matching lower than -10 dB across the 3-5 GHz band. The LNA core consumes only 2.4 mW from 1.2 V supply voltage and 2 mA current.
