Abstract
A bias current generator circuit includes a current path and a leakage control circuit. The current path is connected between a supply voltage and a ground level. The current path includes a transistor and a resistor. The transistor has a current channel connected in the current path. The resistor has an upper terminal and a lower terminal connected in the current path, and a well contact to allow a reverse leakage current of the resistor to flow through. The leakage control circuit is connected to the supply voltage. The leakage control circuit includes a driving transistor to provide a driving voltage to the well contact of the resistor, and to allow the reverse leakage current of the resistor to flow into the leakage control circuit.
