A new LV/LP CMOS four-quadrant analog multiplier designed in a modified bridged-triode scheme (MBTS) is presented. It brings in the benefits in terms of linearity, power consumption, frequency response and total harmonic distortion (THD). The fabricated chip in TSMC 0.35μm n-well SPQM CMOS technology has a nonlinearity error less than 0.8% over ±0.5V input range under a nominal supply voltage of ±1.5V, and consumes the total power dissipation of 2.7 mW only.
