Abstract
An improved capacitive feedback circuit () comprises a feedback capacitor () having its output terminal connected to a high-impedance node (N). More particularly, the improved capacitive feedback circuit comprises a first branch () having a bias current source (), an amplifying element (), and a current sensor () connected in series, the amplifying element having a high-impedance control terminal (). The feedback capacitor () has its output terminal connected to said control terminal (). A current-to-voltage converting feedback loop () has a high-impedance output terminal () connected to said feedback capacitor output terminal.
