Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 18:
19. The method of claim 17, wherein outputting the second voltage signal based on the current signal includes:
receiving the current signal at an inverting input of an operational amplifier through a first switch that is responsive to a second switch signal to selectively connect the current signal to the inverting input during the charging phase;
discharging the second voltage signal through a second switch and a resistor that is in an RC circuit that includes the resistor and a capacitor connected in parallel between the inverting input and an output of the operational amplifier,
wherein the second switch is responsive to the first switch signal to selectively connect the output to the inverting input through the second switch and the resistor during the discharging phase.
