Abstract
Certain aspects of the present disclosure provide circuitry connecting an output of voltage reference circuitry powered by a relatively high voltage to an input of a voltage buffer configured to generate a voltage lower than the high voltage. The connecting circuitry prevents the high voltage from reaching the input of the voltage buffer. One example electronic circuit generally includes a voltage reference circuit configured to be powered by a relatively higher voltage, a buffer circuit configured to generate a relatively lower voltage as compared to the relatively higher voltage, and circuitry coupled between an output of the voltage reference circuit and an input of the buffer circuit, the circuitry being configured to prevent the higher voltage from reaching the input of the buffer circuit.
