Abstract
A wide-range CMOS analog multiplier based-upon a quarter square algebraic identity technique is proposed. The transistors are operated in the both of saturation and ohmic regions. It consists of shunt-feedback buffer and active attenuator circuits that obtained to the voltage regulation circuits. This paper uses 16 transistors and 4 current sources with a ±1.5V power supply. The wide input dynamic range voltage can be achieved reaching the power supply. The bandwidth is rather than 141 MHz and total harmonic distortion is smaller than 0.7%. The results are carried out by PSpice simulation program. © 2005 IEEE.
