Abstract
An oscillator circuit having an amplifier and feedback loop multiplies a generated signal by appropriate selection of capacitance ratios in the feedback loop. In order to isolate this multiplied, high voltage signal, a voltage divider is used to isolate the high voltage portion from the input and output (I/O) of an integrated circuit oscillator core. The multiplied voltage creates a high voltage signal suitable for stylus signal transmission. The divided, and relatively low, voltage is used in the feedback path to stabilize the oscillator core's operation.
