Abstract :
In this paper, an all NMOS voltage-mode four-quadrant analog multiplier, based on a basic NMOS differential amplifier that can produce the output signal in voltage form without using resistors, is presented. The proposed circuit has been simulated with SPICE and achieved -3 dB bandwidth of 120 MHz. The power consumption is about 3.6 mW from a ±2.5 V power supply voltage, and the total harmonic distortion is 0.85% with a 1 V input signal.
