| description | An analog to digital converter includes leakage current correction circuitry to cancel leakage current injected by a reset switch employing a dummy PMOS switch with a shape factor substantially similar to that of the reset switch. An operational amplifier replicates the voltage of the comparator sense input node to the drain of the dummy transistor to create the same operating point as the reset switch. The resulting leakage current is then repeated and fed back to the node to cancel the offending leakage current. |
