摘要:

Disclosed is an electronic delay-producing device using an electrolytic condenser and a constant current source, for charging the condenser. With a constant current source, the voltage vs time curve is linear rather than logarithmic and hence switching may be done at a lower voltage level without sacrificing the length of the time delay. Also, leakage currents and their effects on time delays are reduced. The constant current source is derived from a Darlington pair using a transistor as a non-linear resistor to feed the condenser voltage back to the base of the Darlington pair. The output of the pair remains constant over the desired range of condenser voltage values.
