We propose a highly reconfigurable superheterodyne receiver that employs a 3rd-order
complex IQ charge-sharing band-pass filter (BPF) for image rejection and 1st-order
feedback based RF-BPF for channel selection filtering. The operating RF input frequency of
the receiver is 500 MHz-1.2 GHz with varying high-IF range of 33-80 MHz. All the gain
stages are merely inverter-based gm stages. The total gain of the receiver is 35dB and in-
band IIP3 at midgain is+ 10 dBm. The NF of the receiver is 6.7 dB, which is acceptable for …
