Abstract :
A low-voltage (⩽3 V) CMOS four quadrant multiplier is introduced which has an almost rail-to-rail differential-input-swing with a low signal-distortion (⩽1% for 1 MHz signal, ⩽7% for 100 MHz signal). The proposed circuit is composed of a pair of rail-to-rail differential-input V-I converters and a pair of voltage-followers. This topology of multiplier results in a high frequency capability with low power consumption. In a 1.2 μm n-well CMOS process, the 3 dB frequency of the multiplier is in a range of 103 MHz. The total power consumption is around 0.5 mW with supply voltage 2 V. The multiplier can operate at a minimum supply voltage of 1.8 V
