TLDR
An ultra-low-voltage RF receiver for applications in the 2.4 GHz band, designed in a 90 nm CMOS technology, which has a programmable overall gain of 30 dB, noise figure of 18 dB, out-of-channel IIP3 of -22 dBm.Abstract:
We report an ultra-low-voltage RF receiver for applications in the 2.4 GHz band, designed in a 90 nm CMOS technology. The sliding-IF receiver prototype includes an LNA, an image-reject LC filter with single-ended to differential conversion, an RF mixer, an LC IF filter, a quadrature IF mixer, RF and IF LO buffers, and an I/Q baseband section with a VGA and a low-pass channel-select filter in each path, all integrated on-chip. It has a programmable overall gain of 30 dB, noise figure of 18 dB, out-of-channel IIP3 of -22 dBm. The 3.4 mm2 chip consumes 8.5 mW from a 0.5 V supply.read more

0.5-V analog circuit techniques and their application in OTA and filter design
TL;DR: In this paper, operational transconductance amplifier (OTA) and filter design for analog circuits with very low supply voltages, down to 0.5 V, are presented. But they do not consider the effect of low-voltage analog circuits on the performance.

A CMOS switched transconductor mixer
TL;DR: In this article, the performance of the switched transconductor mixer was compared with the conventional active mixer, demonstrating competitive performance at a lower supply voltage, and the new mixer has a fundamental noise benefit, as noise produced by the switch-transistors and LO-port is common mode noise, which is rejected at the differential output.
