ABSTRACT:
A logic chip that controls the motor of a motorized window covering or other object includes a clock. A frequency stabilizer circuit is provided to receive input voltage and to output to the clock a current that is a function of the voltage and temperature over a range of input voltage values and over a range of ambient temperature values so that the frequency output by the oscillator is constant.
