      abstract     = {Extensional-mode quartz resonators are being increasingly
                      used as force sensors in dynamic scanning force microscopy
                      or atomic force microscopy (AFM). We propose a voltage
                      preamplifier in order to amplify the charge induced on
                      quartz electrodes. The proposed solution has some advantages
                      over the typically used current-to-voltage converters.
                      First, the gain does not depend on the inner parameters of
                      the quartz resonator, which are usually unknown for the
                      specific resonator and may even vary during the measurement.
                      Second, with such an amplifier a better signal-to-noise
                      ratio can be achieved. Finally, we present AFM images of the
                      Si(111) and the SiO(2) surfaces obtained by the voltage
                      preamplifier with simultaneously recorded tunneling
                      current.},
