An integrated analog multiplier circuit

An integrated analog multiplier circuit

The exponential characteristic of the base-emitter Junction in bipolar transistors was used to make an accurate and fairly temperature independent multiplier. Using hybrid-pi transistor models and ECAP, a bandwidth of 350 MHz was predicted. Linearity is limited by emitter degeneration in the input d...

description The exponential characteristic of the base-emitter Junction in bipolar transistors was used to make an accurate and fairly temperature independent multiplier.

The multiplier was fabricated as a monolithic integrated circuit in the Tektronix integrated circuits laboratory. The prototype showed a bandwidth of 200 MHz, and a linearity of 2% over 50% of the dynamic range, when used as a variable gain amplifier. === Graduation date: 1968
