摘要：
A chopped charge pump with matching up and down pulses including a first pair of current sources, a second pair of current sources, and a switching circuit for switching on in a first phase one current source of each pair to provide up current pulses, and the other current source of each pair to provide down current pulses, and switching on in a second phase the other current source of each pair to provide up current pulses, and the one current source of each pair to provide down current pulses to offset error in the current response of the pairs of current sources.
