A Noise Cancelling 0.7-3.8 GHz Resistive Feedback Receiver Front-End in 65 nm CMOS

Summary, in English

This paper presents a noise cancelling 0.7–

3.8GHz receiver front-end implemented in 65nm technology.

The circuit has a main path consisting of a high input

impedance gm-stage, current-mode passive mixers and baseband

amplifiers, where the input match is provided by frequency

translational negative feedback from baseband to RF

input. An auxiliary path with tunable gain is introduced to

cancel noise from the main path while maintaining linearity.

The receiver front-end achieves a noise figure of 1.6–3.7dB

and an IIP2 and IIP3 of >75dBm and >1dBm, respectively.

The current consumption of the circuit is 22.8–34.9mA, from

a 1.2V supply.
