ABSTRACT:
An integrated electrostatic discharge (ESD) protection circuitry for a signal electrode. Coupled in shunt between the signal electrode and the positive and negative power supply electrodes are opposing sets of multiple diodes coupled in series. Each set includes a diode across which is applied a nominal reverse bias voltage. These opposing reverse bias voltages are maintained at substantially constant predetermined nominal magnitudes in relation to the voltage at the signal electrode, thereby ensuring minimal leakage current via the signal electrode over the full dynamic range of the signal.
