A novel type of analogue multiplier-cum-divider is described. A square waveform of period T which is proportional to V2/V1, where V2 and V1 are the two input applied voltages, is generated. Another input voltage V3 is integrated during the period T. The peak value of the integrated output is V2V3/V1. © The Institution of Engineering and Technology 2013.

A new analogue divider circuit by averaging a triangular wave using operational amplifiers is explained in this paper. The triangle wave averaging analog divider using operational amplifiers is explained here. The reference triangular waveform is shifted from zero voltage level up towards positive power supply voltage level. Its positive portion is obtained by a positive rectifier and its average value is obtained by a low pass filter. The same triangular waveform is shifted from zero voltage level to down towards negative power supply voltage level. Its negative portion is obtained by a negative rectifier and its average value is obtained by another low pass filter. Both the averaged voltages are combined in a summing amplifier and the summed voltage is given to an op-amp as negative input. This op-amp is configured to work in a negative closed environment. The op-amp output is the divider output. © 2017, The Institution of Engineers (India).
