Apparatus and associated methods relating to a switch leakage compensation delay circuit include a compensating transistor configured to passively bypass a leakage current around a capacitor that connects in series with a control transistor. In an illustrative example, the capacitor and the compensating transistor may be connected in parallel between a first node and a second node. The compensating transistor gate may be tied, for example, directly to its source and to the second node. The control transistor may connect its drain to the second node. When a control signal turns off the control transistor, a leakage current of the control transistor may be supplied from a leakage current of the compensating transistor such that the voltage across the capacitor may be maintained substantially constant. The delay circuit may advantageously mitigate the capacitor’s voltage droop to reduce clock time skew, for example, in low speed interleaved ADC operation.
