Abstract: An amplification apparatus includes an amplifier having an inverting terminal, and a non-inverting terminal connected to a reset voltage node, a first capacitor connected to the inverting terminal, an input voltage being applied to the first capacitor, a second capacitor connected to the inverting terminal and an output terminal of the amplifier, and a duty-cycled resistor, connected in parallel to the second capacitor, including a first resistor. The duty-cycled resistor is configured to connect the first resistor and the inverting terminal and to disconnect the first resistor and the reset voltage node during a first time interval included in a period to complete an on-and-off cycle of the duty-cycled resistor, and disconnect the first resistor and the inverting terminal and to connect the first resistor and the reset voltage node during a second time interval included in the period.

Abstract: An impedance measuring apparatus is disclosed. The impedance measuring apparatus includes an input current generator configured to generate a sinusoidal input signal of a carrier frequency, a first electrode configured to apply the sinusoidal input signal to an object which has an impedance, a second electrode configured to receive an amplitude modulated signal from the object, a first amplifier configured to amplify the received amplitude modulated signal and output a first amplified signal, a baseline signal subtractor configured to subtract a baseline signal generated based on the first amplified signal from the amplitude modulated signal and output a subtraction modulated signal, an analog-to-digital converter (ADC) configured to convert the subtraction modulated signal to a digital modulated signal, and an impedance measurer configured to measure the impedance based on the digital modulated signal.
