ABSTRACT:
A drive circuit (18) is provided that utilizes a power supply (30) to generate an output voltage that effects a precise displacement in a physical device. The drive circuit (18) includes storage circuitry (26) having a capacitive load (54) for storing the output voltage, a supply switch (34) connected the to the storage circuitry (26), the power supply (30), and control circuitry (22) that controls the supply switch (34) in response to an input signal. The control circuitry (22) controls the supply switch (34) in response to the input signal such that a supply voltage (31) from the power supply (30) is intermittently applied to the capacitive load (54) of the storage circuit (26) for generation of the output voltage that is used to effect a precise displacement in a physical device.
