Abstract :
An analog CMOS current multiplier building block for low voltage applications using an n-well process is presented. The multiplier equations are derived to proof its linear characteristic, and then a low voltage design is proposed. Post layout simulation in a 0.35 mum AMS CMOS process and 1.5 V supply voltage shows a THD of 0.84% at 10 MHz and a frequency response bandwidth of 140 MHz.
