Abstract
An apparatus, method, and system for converting a charge to a voltage.
Claims20
A charge to voltage (Q2V) converter for converting a charge to a voltage, the Q2V converter comprising:
- a pair of push-pull source followers;
- and
- a set of alternating current (AC) coupling capacitors coupled to each of the push-pull source followers.
A method for converting a current pulse to a voltage, the method comprising:
- closing a set of reset switches of a charge to voltage (Q2V) converter to reset values in the Q2V converter;
- wherein the Q2V converter comprises a set of bias nodes;
- and
- shorting the set of bias nodes of the Q2V converter.

A system for converting charge to voltage, the system comprising:
- a charge to voltage (Q2V) converter;
- wherein the Q2V converter comprises a set of reset switches, a set of successive-approximation-register (SAR) input capacitors, and a set of bias nodes;
- and
- logic enabling the Q2V converter to:
- close the set of reset switches to reset values in the Q2V converter;
- short the set of bias nodes of the Q2V converter;
- and
- connect the set of SAR input capacitors of the Q2V converter.
