摘要：In one embodiment, a constant-current generator is connected in series with adependent (e.g., tail) device. A switched capacitor circuit connected to the gate of thedependent device is operated to (i) charge at least one capacitor of the switchedcapacitor circuit, (ii) use the at least one charged capacitor to adjust the gate voltage of
the dependent device to drive the dependent current through the dependent device tobe equal to the constant current through the constant-current generator, and (iii) directthe dependent and constant currents through source and sink current nodes.
