Abstract
A position indicator has a first electrode, an inverting amplifier and electrical isolation circuitry. The first electrode, in operation, receives an input signal from a capacitive touch panel and transmits a reference signal. The inverting amplifier has an input coupled to the first electrode, and, in operation, inverts and amplifies the input signal. The electrical isolation circuitry has an input coupled to an output of the inverting amplifier, and, in operation, generates the reference signal based on the inverted and amplified input signal.
