Abstract: One embodiment relates to an apparatus configured to cancel charge injected on a node of a differential pair of nodes. A dummy circuit element can inject charge on an inverted node to cancel charge injected on a non-inverted node by a switch when the switch is switched off. In addition, another dummy circuit element can inject charge on the non-inverted node to cancel charge injected on the inverted node by another switch when the other switch is switched off. These dummy circuits elements can be cross-coupled.

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.

Abstract: A common mode feedback (CMFB) loop for a differential amplifier sense an output common mode of a differential circuit and provides feedback to the gates of tail current transistors. Many CMFB loops cannot easily adjust the output common mode voltage and the output common mode may vary over process, voltage, and temperature. An improved CMFB circuit adds a control circuit to control backgates of tail current transistor device(s) of the differential circuit such that the output common mode voltage can be made adjustable.
