dc.description.abstractA multicell amplifier is developed by connecting floating signal modules in series to drive piezoelectric devices. The amplifier generates a high voltage gain by summing the individual module gains. The bandwidth equals that of a single module. The multicell amplifier provides a means of achieving high power and can divide the total power dissipation among the modules, because each module delivers the same output voltage and current. A prototype circuit that consists of six floating signal modules exhibits precise linear operation over a wide range of input frequencies and capacitive loads. The circuit provides a 200-V output swing with a corner frequency of around 100 kHz at a driving capacitive load of 0.1 mu F. The slew rate is as high as 115 V/mu s, and the maximum output current is +/- 2.6 A. The practicality and performance of the presented modular implementation concepts were verified by the close match between the simulated and experimental results.en_US
