Abstract :
A low-voltage four-quadrant multiplier using floating-gate MOSFETs is presented. This circuit has been implemented in a 0.8 μm double-poly double-metal CMOS process. Experimental results show that for a single power supply of 2.5 V, the total harmonic distortion is less than 1.4% with input range up to 1Vp.p. The modulation application of this multiplier call be operated over 20 MHz. Moreover, it can operate satisfactorily regardless of the transistor body connection. This circuit is expected to be useful in low-voltage analogue signal-processing applications
