A Study and Comparison of Low Voltage CMOS Current Multiplier

A study and comparison between current mode CMOS analog multiplier, CMOS current mode multiplier/divider and high frequency four quadrant current multiplier has been carried out in this paper. Current multiplier has been simulated in SPICE with 0.35μm, 0.5μm. Simulation have been done with supply voltage of 3.3V, 1.5V and 1.55V respectively. The simulated results show that characteristic of mul...

Voltage Differencing Buffered Amplifier based Voltage Mode Four Quadrant Analog Multiplier and its Applications

In this paper a voltage mode four quadrant analog multiplier (FQAM) using voltage differencing buffered amplifier (VDBA) based on quarter square algebraic identity is presented. In the proposed FQAM the passive resistor can be implemented using MOSFETs operating in saturationregion thereby making it suitable for integration. The effect of non idealities of VDBA has also been analyzed in this pa...

Novel Current-Mode Four-Quadrant CMOS Analog Multiplier/Divider

This paper presents, a new current mode four-quadrant CMOS analog multiplier/divider based on dual translinear loops. Compared with the previous works this circuit has a simpler structure resulting in lower power consumption and higher frequency response. Simulation results, performed using HSPICE with 0.25um technology, confirm performance of the proposed circuit.

An analog CMOS four quadrant current-mode multiplier for low power artificial neural networks implementation

A CMOS four-quadrant analog multiplier circuit for neural networks integrated circuit implementation is presented. By applying differential balanced current mode signals (both for the input, output and weight signals) the multiplication function is easily implemented through two translinear loops. The multiplier exhibits low power consumption (the dc current is 250 nA under a differential power...
