A microphone assembly is provided that includes a condenser transducer element having a displaceable diaphragm and a back-plate. The displaceable diaphragm and the back-plate are arranged to form a capacitor in combination. A preamplifier circuit has an input stage, the input stage comprising a P-type field effect transistor. The displaceable diaphragm and the back-plate are operatively connected between a source input and a gate input of the P-type field effect transistor.
