Abstract
A low voltage signal amplifying apparatus includes a probe device, an actuator providing relative motion between the probe device and the sample, and a transducer that generates a voltage signal indicative of a property of at least one of the probe device, the sample, and the actuator. A differential voltage to current converter receives a differential voltage signal from the transducer and generates a differential current signal to provide a balanced, differential, low impedance current mode amplified signal that can be readily carried over a signal transmission device.
