Comparison of Current Modes in CMOS Analog Multipliers
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 5
Abstract
A study and comparison between current mode CMOS analog multiplier, ±1.5 V High frequency four quadrant current multiplier and ±1.2 V High frequency four quadrant current multiplier has been carried out in this paper. Current multiplier has been simulated in SPICE with 0.35µm and 0.5µ m technology. Simulation has been done with supply voltage of 3.3V,1.5V and 1.2V respectively. The simulated results show that characteristic of multipliers are linear with 10µA, 30µA and 20µA input range respectively and power dissipation of ±1.2 V High frequency four quadrant current multiplier is less as compared to the other circuits in 0.35 µm and 0.5 µm technology. These circuits are widely used for analog signal processing application.
