ABSTRACT
The peak value of the integrated voltage is proportional to the product of the input voltages. A square/triangular waveform whose time period is proportional to one voltage is generated. Another input voltage is integrated during the time period. The peak value of the integrated voltage is proportional to the product of the input voltages. This is called double dual-slope peak responding multiplier (PRM). A rectangular pulse waveform whose OFF time is proportional to one voltage is generated. Another voltage is integrated during this OFF time. The peak value of the integrated output is proportional to the product of the two input voltages. This is called a pulse width integrated PRM. At the output of a PRM, if a peak detector is used, it is called a peak detecting multiplier, and if a sample and hold is used, it is called a sampling multiplier.
