Reconfigurable measuring apparatus and method for controlling apparatus

摘要

A reconfigurable measuring apparatus includes a first chopper configured to modulate an input signal, and an amplifier configured to amplify an output signal of the first chopper. The reconfigurable measuring apparatus further includes a second chopper configured to demodulate an output signal of the amplifier, and a controller configured to control the first chopper and the second chopper based on a measurement mode.

1. A reconfigurable measuring apparatus comprising:
a first chopper configured to modulate an input signal; an amplifier configured to amplify an output signal of the first chopper; a second chopper configured to demodulate an output or internal signal of the amplifier; and a controller configured to control the first chopper and the second chopper based on a measurement mode, wherein the controller is configured to control the first chopper to modulate the input signal in response to the measurement mode being a biopotential measurement mode, and wherein the controller is configured to control the first chopper to pass the input signal unmodulated in response to the measurement mode being an impedance measurement mode.
