Abstract: A receiver includes a low noise amplifier (LNA), a passive mixer, a passive filter, a baseband processing block and a voltage controller. The LNA receives and amplifies a radio frequency (RF) signal. The passive mixer is coupled to the LNA without any AC coupling capacitance therebetween, and generates an intermediate frequency signal by down-converting the RF signal. The passive filter filters the intermediate frequency signal. The baseband processing block includes a transimpedance amplifier (TIA) and processes the filtered intermediate frequency signal. The voltage controller keeps a first node and a second node of a signal path to be around a common DC voltage, wherein the first node is located between an output terminal of the LNA and an input terminal of the passive mixer, and the second node is located between an output terminal of the passive mixer and an output terminal of the TIA.

Abstract: An interference-robust receiver includes an RF signal processor, a frequency conversion interface and an analog signal processor. The RF signal processor provides an RF signal. The frequency conversion interface includes a passive mixer for generating an intermediate frequency signal by down-converting an in-band part of the RF signal to a passband of a filter and down-converting an out-of-band part of the RF signal to a stopband of the filter. The filter can thus filter the intermediate frequency signal with the passband and the stopband.
