An apparatus comprising a delay circuit and a control circuit. The delay circuit may be configured to generate a plurality of intermediate signals in response to (i) a clock signal and (ii) an adjustment signal. The control circuit may be configured to generate the adjustment signal and a plurality of output signals having a quarter-cycle interval in response to (i) the plurality of intermediate signals and (ii) the clock signal.

Generating signals with accurate quarter-cycle intervals using digital delay locked loop

An apparatus generally having a first circuit, a second circuit and a third circuit is disclosed. The first circuit may be configured to selectively switch a bonding pad to (i) a first rail of a power source and (ii) a discharge rail in response to an electrostatic discharge. The second circuit is generally configured to clamp the electrostatic discharge between the discharge rail and the first rail. The third circuit may be configured to bias the discharge rail to a second rail of the power source.
