In electronics, an analog multiplier is a device which takes two analog signals and produces an output which is their product. Such circuits can be used to implement related functions such as squares and square roots. An electronic analog multiplier can be called by several names, depending on the function it is used to .

An analog multiplier is a device having two input ports and an output port. The signal at the output is the product of the two input signals. If both input and output signals are voltages, the transfer characteristic is the product of the two voltages divided by . The AD6is a functionally complete, four-quadrant, analog multiplier. It includes high impedance, differential X and Y inputs, and a high impedance summing input (Z). The low impedance output voltage is a nominal V full scale provided by a burie.

In addition to multiplying and dividing, multipliers can perform squaring, square-rooting and modulation functions. Applications include radar . This part is RoHS compliant. The MPY6is a wide bandwidth, high accuracy, four- quadrant analog multiplier.

Its accurately laser-trimmed multiplier characteristics make it easy to use in a wide variety of applications with a minimum of external parts, often eliminating all external trimming. Its differential X, Y, and Z inputs allow configuration as a . Simple circuit technique for implementing four-quadrant analog multiplier has been presented. The proposed circuit requires only operational amplifier (opamp ) as the active element. The realization method is based on the quarter-square technique where a square is provided from the inherent quadratic behaviour of . The voltage output simplifies many designs by eliminating the current-to-voltage conversion stage required for current output multipliers.

These devices can directly multiply battery current by an input voltage from to 1V. The circuit presented improves the measurement accuracy by feeding the ADC reference voltage to . The important applications of these multipliers are multiplication, division, squaring and square – rooting of signals, modulation and demodulation. It is obviously possible to use different values to. Abstract approved: James C. Analog multiplier diagram.

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 3MHz was . A CMOS analog multiplier is described with a wide voltage range similar to that of commercially available bipolar multipliers.

MHz bandwidth o Low power dissipation. A new circuit configuration for an MOS four-quadrant analog multiplier circuit is presented. It is based on the square-law characteristics of the MOS transistor.

Two versions have been realized. The first has a linearity better than 0. In the present, the most .
