Abstract:
Systems and devices are provided for fully discharging leakage current generated during standby and/or power down modes regardless of variations in PVT conditions. An apparatus may include a power generation unit that powers components of the apparatus and a bleeder circuit. The bleeder circuit may include an operational amplifier. Further, the bleeder circuit may include leakage current generator circuitry that is coupled to the operational amplifier and generates a first current that mimics leakage current generated by the power generation unit. Furthermore, the bleeder circuit may include leakage current mirroring circuitry that is coupled to an output of the operational amplifier and that generates a second current that mirrors the first current. In addition, the bleeder circuit may also include leakage current bleeder circuitry that is coupled to the leakage current mirroring circuitry and that generates a third current that sinks the leakage current to ground.
