ABSTRACT:
A multiplying digital to analog converter comprising a digital to analog converter having a plurality of capacitors coupled in parallel, applying first signals to the capacitors during a sampling period, and applying second signals to the capacitors during an amplifying period, and an amplifier including a first amplifier electrically coupled to the digital to analog converter; a second amplifier electrically coupled to the first amplifier; and a first switch electrically coupled between an input end and an output end of the second amplifier, being turned off during a sampling period, and being turned off during an amplifying period.
