  • Low voltage CMOS analog multiplier with extended input dynamic range
    Patent number: 5872446
    Abstract: A low voltage CMOS multiplier uses a transconductance stage to generate a dynamic bias current which is used to compensate for non-linear terms in a Gilbert Cell multiplier circuit. Common mode dependence is minimized by using balanced differential input stages for both the transconductance and multiplier stages.
