A Novel Wide-Swing Wide-Bandwidth Scalable Low-Voltage Analog CMOS Multiplier for Communication Signal Processing

This paper reports a novel scalable CMOS four-quadrant multiplier design with wide-signal swing and wide bandwidth enabling numerous applications in communication signal processing. The multiplier operates in a scalable voltage range between 3.3V and 1V power supply with a maximum input dynamic range of 500mV(@3.3V supply) at both the inputs (multiplier & multiplicand inputs) and a -3dB bandwidth of around 1GHz. The simulations were carried out using the 3M1P 0.5um Agilent (HP) CMOS (with 3.3V supply) and the 5M1P 0.18um TSMC CMOS (with 1V Supply) process technologies. The typical THD (Total Harmonic Distortion) for the multiplier was around -56dB. The multiplier was found to dissipate a mere 1mW from a 1V supply.
