Abstract
A substrate bias pump is provided with a signal controlled circuit for coupling a negatively charged pump node to a substrate with a negligible voltage loss therebetween. A transistor, connected as a capacitor, with a source and a drain connected together for receiving a pump signal, and a gate connected to the pump node, avoids adding parasitic capacitance to the pump node.
