Figure 1c illustrates variable gain amplifier 106 according to an embodiment of the present invention. Variable gain amplifier 106 includes attenuator 126 followed by amplifier 128. In an embodiment, attenuator 126 may be implemented using a selectable capacitor array, a selectable resistor array, or other active or passive attenuator structures. In an embodiment, the selectable resistor array may be used to shift the corner frequency of an electrical high-pass transfer function in order to provide an adjustable attenuation, where the lower corner frequency is a function of the capacitance of the capacitive sensor and the input impedance of IC 100. Amplifier 128 converts single ended input signal 127 to differential output signal Vp and Vn. Attenuator 126 and amplifier 128 may be implemented using circuits described in co-pending applications 13/183,193 and 13/217,890, or using other amplifier structures known in the art. Alternatively, the gain of amplifier 128 may also be controlled by gain control signal GC1.
