摘要：

In this paper, we propose a digital programmable OTA-based multi-standard receiver for analog baseband chain. It consists of a switchable-order low-pass filter and two programmable gain amplifiers (PGAs). The low-pass filter has a cutoff frequency that can be digitally tuned from 1 MHz to 10.2 MHz. Thus, it covers Bluetooth, UMTS, DVB-H and IEEE 802.11a/g standards. The gain of each PGA can be varied from 0 dB to 35 dB with a gain step of 5 dB. The proposed multi-standard receiver is designed and simulated in 90 nm CMOS technology under +/- 0.6 V supply voltage. The overall simulation results show a variable gain from 0 dB to 70 dB, switchable-order (2nd/4th/6th) frequency response, in-band IIP3 of 21.9 dBm, and input referred noise of 102.6 nV/root Hz at 1 MHz with total power consumption of 11.77 mW.
