Abstract
A low voltage to high voltage (LV2HV) conversion circuit has an input configured to receive an input signal (at a relatively low voltage) and an output configured to generate an output signal (at a relatively high voltage). The LV2HV conversion circuit includes a voltage to current conversion circuit referenced to the relatively low voltage and configured to convert a voltage of the input signal to a first current, wherein a magnitude of the first current is dependent on said voltage of the input signal and a gain setting value. A current mirroring circuit mirrors the first current and outputs a second current. A current to voltage conversion circuit converts the second current to a voltage of the output signal. The current mirroring circuit and current to voltage conversion circuit are referenced to the relatively high voltage.
