Abstract
A charge pump provides matched charging and discharging currents. One transistor is connected to an input of a charge pump core while two transistors are connected to the other input of the charge pump core, with each of the transistors mirroring a reference transistor through different mirroring pathways so that current through the transistor of the first input is equal to the sum of currents through the two transistors of the second input.
