  • Instrumentation amplifier
    Patent number: 9634626
    Abstract: An instrumentation amplifier includes: a capacitive feedback closed-loop amplifier, an input capacitor charging module, a feedback capacitor discharging module, a noise separation module and a logic controller. The capacitive feedback closed-loop amplifier includes a fully differential operational amplifier, a first input capacitor, a second input capacitor, a first feedback capacitor and a second feedback capacitor. The input capacitor charging module is configured to charge the first input capacitor and the second input capacitor periodically. The feedback capacitor discharging module is configured to discharge the first feedback capacitor and the second feedback capacitor periodically. The noise separation module is configured to separate a noise from a signal using a chopping modulation technology. The logic controller is connected to the input capacitor charging module, the feedback capacitor discharging module and the noise separation module to control the modules to operate.
