Systems and devices are provided for tracking bandgap current generated by a bandgap circuit and mitigation of leakage current regardless of variations in PVT conditions. An apparatus may include one or more power amplifiers that powers components of the apparatus and comprising a transistor. The apparatus may also include bandgap current mirroring circuitry that generates a mirrored current that mirrors a received current that is process, voltage, and temperature (PVT) independent. The apparatus may also include a bulk voltage generator circuit including an amplifier having an input coupled to the bandgap current mirroring circuitry. Bulk voltage control circuitry is coupled to an output of the amplifier and generates a bulk voltage based on the relationship between the mirrored current and the leakage current.
