| 摘要 | A high speed four quadrant multiplier is current controlled and uses a high speed differential output current digital to analog converter. Independent adjustment of the multiplying factor without changing the DC offset is accomplished. Also a true zero input signal will cause a true zero output signal and the operation of the multipler is extremely fast. The analog throughput of the multiplier is independent of the speed of the digital to analog converter. | ||||||
