摘要
A switched-capacity amplifier formed from integrated capacities has undesirable parasitic capacities that are large and variable on only one terminal of each of the capacities. A voltage-follower stage is connected to this terminal of each of the capacities (except those capacities which are grounded) to offset the parasitic capacity. The amplifier is also connected in a switched-capacity filter and a charge-transfer filter.
