Abstract
A charge domain digital-analog multiplier device. The device has one analog input, M-parallel digital inputs, and one analog output. An M-bit digital word signal is applied to the digital inputs and an analog signal is applied to the analog input. The output is a charge packet which is proportional to the product of the analog input signal and the digital word.
