ABSTRACT:
An integrating circuit includes first and second amplifiers for use during a zero-integrate mode and a X10 mode, respectively. The first amplifier is a low gain amplifier to ensure stability, whereas the second amplifier is a high gain amplifier to improve accuracy. During the zero-integrate mode, switches couple an integrator input lead to the first amplifier output lead and decouple it from the second amplifier output lead. During the X10 mode, the switches decouple the integrator input lead from the first amplifier output lead and couple it to the second amplifier output lead.
