ABSTRACT:
A substrate pump circuit for generating a negative bias on the substrate of a semiconductor device employs a capacitor coupling an oscillator output to a pump node, and MOS diodes coupling the pump node to a ground terminal and to the substrate node; the MOS diode for the substrate node is reconfigured as an active switch, controlled by a complementary pump circuit. This circuit allows transfer of more charge from the pumping capacitor to the substrate capacitance on each pump cycle. Also, pumped charge is delivered directly to the substrate through ohmic connections, rather than through forward biased injecting junctions.
