Title:
INTEGRATOR RESET MECHANISM
Document Type and Number:
WIPO Patent Application WO2005011122
Kind Code:
A3
Abstract:
An integrator with a reset mechanism comprises an integration capacitor and a replacement integration capacitor, wherein the integration capacitor is replaced with the replacement integration capacitor during a reset operation. A method of resetting an integrator comprises temporarily removing an integration capacitor and replacing the integration capacitor with a reset capacitor during a reset operation of the integrator. The method may further comprise temporarily removing the integration capacitor and replacing it with a reset capacitor multiple times during a single reset operation of the integrator.
