摘要 |
A multiphase multiplier circuit employs analog switches, each of which is duty controlled for multiplying input voltage signal with a multiplier determined depending on the duty cycle ON/OFF period. The multiphase multiplier circuit further includes means for multiplying a reference voltage signal by a desired factor for deriving the difference between the product and the factor for controlling duty cycles of the analog switches. |
