A new low power 5.6 GHz doubly balanced sub-harmonic mixer for industrial scientific medical (ISM) band direct conversion - zero IF receiver in 0.25-/spl mu/m CMOS is presented. The mixer uses a power efficient LO frequency generation scheme to overcome the LO self-mixing problems common in conventional direct conversion receivers (DCR). Simulated with 1% gm mismatch, 0.5% load mismatch and 2/spl deg/ LO phase error, the mixer is able to achieve 55 dBm of IIP2, -6.5 dBm of IIP3 and voltage… CONTINUE READING
