Abstract

See full text

Conventional bias circuits exhibit a number of limitations, including the time required to power-up a bias circuit following a low-power state. Large current surges in the supply network induce ringing, further complicating a power-up process. Example embodiments reduce power-up time and minimize current surges in the supply by selectively charging and discharging capacitance to the circuit during power-up and power-down of the bias circuit.
