In this paper a low voltage low power multiplier circuit based on the Gilbert Cell is presented. Spice simulation using 180nm technology is carried out to demonstrate the working of the proposed circuit. Power dissipation of the circuit is 0.0755mW. The -3dB bandwidth of this multiplier is 26.73GHz. Analog multipliers are extensively used in analog signal processing and communication systems such as mixers in FM receivers, amplitude modulators and frequency translators. Analog voltage multiplication can be performed either by using the square law characteristic of MOS transistors biased in saturation region or by using Gilbert Cell.
