Abstract
A 30-mW multi-band receiver based on harmonic
selection is presented. The prototype receiver employs a 32-phase
non-overlapping local oscillator (LO) and is capable of simul-
taneously receiving multiple wireless signals arbitrarily located
between 600 MHz and 3 GHz. The receiver achieves 2.4–5-dB
noise figure (NF) and tolerates as large as −10-dBm out-of-
band blockers. Employing a digital harmonic rejection (HR)
calibration to overcome phase and amplitude mismatches in the
32-phase LO and down-
