Abstract
A frontend circuit for a radio frequency (RF) receiver comprises an RF amplifier circuit to receive an RF signal, a local oscillator (LO) circuit to produce a LO signal, a mixer circuit configured to mix the RF signal with the LO signal to produce a down-converted intermediate frequency (IF) signal, a transimpedance amplifier (TIA) circuit to receive the IF signal, and an error reduction circuit operatively coupled to the TIA circuit and configured to reduce voltage error caused by error charge from parasitic capacitance of the frontend circuit.
