Abstract
A linear interpolator comprising an amplifier, an integrator for integrating an output of the amplifier, a feedback circuit connected between the amplifier and the integrator for bootstrapping an input voltage of the amplifier by an output voltage from the integrator, and a switch for periodically supplying a staircase input signal to the amplifier. A linearly interpolated output is derived from the integrator. The discrete input signal changing stepwise can be linearly interpolated with high accuracy.
