ABSTRACT:
A current controlled switch to compensate for switching time variations. A compensated current source is configured to operate with a current mirror to set the switching current. The control of the switching current maintains control of the peak switching current in the switch, therein controlling the switching transition time. The speed performance is maintained nearly uniform as circuit and process variations cause switching conditions to change. Applications such as delay lines, output buffers, inverters and ringing oscillators are available using the current controlled switching technique of the present invention. Also, parasitic effects can also be compensated by using the present invention.
