Abstract :
A down-converter insensitive to 2nd and 3rd harmonics and a digital assisting circuit that cancels residual sensitivity due to device mismatches are proposed. Measured 2nd and 3rd harmonic rejection ratios of over 60 dB are achieved. This performance allows a simple RF filter, and it is effective to reduce the die size.
