<P>PROBLEM TO BE SOLVED: To provide a process, voltage, temperature, a compensation circuit, and a method of continuously generating a delay amount. <P>SOLUTION: The compensation circuit includes two delay lines, each delay line providing a delay output. The two delay lines may each include a number of delay elements, which in turn may include one or more current-starved inverters. The number of delay lines may differ between the two delay lines. The delay outputs arc provided to a combining circuit that determines an offset pulse based on the two delay outputs and thereafter averages the voltage of the offset pulse to determine a delay amount. The delay amount may be one or more currents or voltages indicating an amount of PVT compensation to be applied to input or output signals of an application circuit, such as a memory-bus driver, a dynamic random access memory, a synchronous DRAM, a processor or other clocked circuit. <P>COPYRIGHT: (C)2011,JPO&INPIT |
