Abstract
A supply bias circuit in which supply current is provided through a resistor coupled to a timing circuit such that this resistor acts as a low pass filter in conjunction with the timing capacitor. Supply current is passed from the timing current through a second resistor and into logic circuitry. The logic circuitry is further connected to the timing circuitry so that it receives extra current each time the capacitor discharges.
