Abstract
Herein disclosed are systems and circuitry for protecting against overdrive and electrostatic discharge. For example, protection circuitry may include field effect transistors to discharge overdrive outside of an operational voltage range of a circuit in some embodiments to prevent damage to the circuit. Further, the protection circuitry may utilize diode features inherent in the field effect transistors to protect against electrostatic discharge in some embodiments. The circuitry may be implemented in radio frequency sampling analog-to-digital converters and can provide for single-ended signal input and/or output for the analog-to-digital converters.
