<p>The present invention provides a voltage regulator (71) especially adaptable for use with a field-programmable gate array (FPGA). The voltage regulator of the present invention rapidly generates an operating voltage for the core or nucleus logic elements upon application of external power while preventing degradation of the fuses. The core or regulated voltage of an FPGA can be set to a level that provides maximum performance with minimum power consumption or, alternatively, permits propagation delays and switching rates to be adjusted so as to compensate for die to die variation. Since it is common for electrical parameters of FPGA manufactured in different wafer fabrication facilities to vary, the voltage regulator (71) is configurable as a true voltage regulator providing its output through a switching transistor (198) or, alternatively, as a pseudo-voltage regulator providing its output through a switching transistor (188).</p> |
