METHOD AND APPARATUS FOR USE IN SWITCHED CAPACITOR SYSTEMS

摘要

Systems, methods, and integrated circuits employ switch capacitor technology for digital to analog conversion. In one embodiment a DAC receives a multi-bit digital signal. The DAC has a switch capacitor network with a plurality of sub DACs. Each of the sub DACs receives an associated bit of the multi-bit digital signal. The capacitance within each of the sub DACs receives an amount of charge in response to the associate bit. At least two of the sub DACs share charge with one another, and the network outputs at least one analog signal indicative of a sum of values of each bit in the multi-bit digital signal.
