Abstract
Provided is a preamplifier with an active deadtime control circuit, which may include: an operational amplifier to which input current and common voltage are applied; a feedback capacitor of which both ends are connected to a first input terminal of the operational amplifier to which the input current is applied and an output terminal of the operational amplifier; a comparator comparing output voltage converted from the input current by the operational amplifier, and reference voltage to output a comparison signal; and a Monostable circuit outputting a switching signal for switching charging or discharging of the feedback capacitor based on the comparison signal.
Claims10
A preamplifier with an active deadtime control circuit, comprising:
- an operational amplifier to which input current and common voltage are applied;
- a feedback capacitor of which both ends are connected to a first input terminal of the operational amplifier to which the input current is applied and an output terminal of the operational amplifier;
- a comparator comparing output voltage converted from the input current by the operational amplifier, and reference voltage to output a comparison signal;
- and
- a Monostable circuit outputting a switching signal for switching charging or discharging of the feedback capacitor based on the comparison signal.
A method for driving a preamplifier with an active deadtime control circuit, comprising:
- (a) applying input current and common voltage to an operational amplifier;
- (b) outputting a comparison signal through a comparator comparing output voltage converted from the input current by the operational amplifier, and reference voltage;
- and
- (c) outputting a switching signal for switching charging or discharging of a feedback capacitor having both ends connected to a first input terminal of the operational amplifier to which the input current is applied, and an output terminal of the operational amplifier based on the comparison signal through a Monostable circuit.
