IEDM'17, San Francisco, CA, Dec. 2017, pp. Although analog multiplier circuits are very similar to operational amplifiers, they are far more susceptible to noise and offset voltage-related problems as these errors may become multiplied. A dc voltmeter can be calibrated as a phase angle voltage divider circuit the division is achieved by connecting the multiplier 0000182543 00000 n 0000002614 00000 n multiplier output will not saturate. 0000012112 00000 n achieved.
