Abstract
An anti process variation self-adjustable on-chip oscillator has been disclosed according to the present invention. The on-chip oscillator includes the following components integrated on a same chip: a reference oscillation unit for producing reference pulse; an oscillation unit to be adjusted for producing output pulse; and a self-adjustable logic control unit for receiving the reference pulse and output pulse, and for transmitting a corresponding adjustment signal to the oscillation unit to be adjusted based on the received reference pulse and output pulse to control the oscillation unit to be adjusted to perform the frequency adjustment to the output pulse. The reference pulse required for adjusting the frequency can be generated by the reference oscillation unit integrated on-chip, so that self-adjustment can be achieved on-chip, decrease the cost of the chip compared with off-chip adjustment.
