ABSTRACT:
The present invention discloses techniques for reducing the low ambient temperature current consumption of circuits used along with sensing circuits in Programmable Logic Devices. Further, according to the present invention the supply voltage noise is substantially prevented from reaching the input of the sensing circuits of a Programmable Logic Device. In one embodiment, the present invention comprises a combination of a comparator, a reference voltage generator circuit, and a reference current and voltage generator circuit, which combination enables the present invention to substantially prevent the supply voltage noise from reaching the input of the sensing circuit of a Programmable Logic Device. Moreover, the present invention provides a technique for the reduction of the effect of semiconductor processing variations on the voltage of theh output signal of the present invention's temperature reference circuit. As such, the output of the temperature reference circuit of the present invention is a more accurate representation of the ambient temperature variations rather than semiconductor processing variations.
