Abstract
The building blocks of a 0.5-V receiver, including a receiver front-end and a low-pass filter (LPF), are fabricated using 0.18-μ CMOS technology. At 5.6 GHz, the receiver front-end achieves a voltage gain of 17.1 dB and a noise figure of 8.7 dB, while dissipating at 19.4 mW. The fifth-order low-pass Chebyshev filter achieves a corner frequency of 2.6 MHz and an input-referred noise of 28.5 nV/sqrt (Hz) at 6.8 mW. The receiver front-end is further integrated with the LPFs to form a highly integrated receiver subsystem at ultra-low voltage.
