Abstract
A signal amplification method includes receiving, from a capacitive sensor, a first input signal by a first control terminal of a first transistor, and a second input signal by a first control terminal of a second transistor. The method also includes producing a first output signal, including amplifying a first signal at a first load path terminal of the first transistor using a first inverting amplifier having an output coupled to a resistance network, and producing a second output signal, including amplifying a second signal at a first load path terminal of the second transistor using a second inverting amplifier having an output coupled to the resistance network. The method also includes feeding back the first and second output signal to a second load path terminal of the first transistor and to a second load path terminal of the second transistor via the resistance network according to a pre-determined fraction.
