Abstract
A programmable logic device comprising a core circuit, a first circuit, a second circuit, and a third circuit. The core circuit may be configured to (i) operate at a first supply voltage, (ii) receive one or more internal input signals, and (iii) generate one or more internal output signals. The first circuit may be configured to generate said first supply voltage in response to a second supply voltage. The second circuit may be configured to (i) operate at a third supply voltage and (ii) generate said one or more internal input signals in response to one or more external input signals. The third circuit may be configured to (i) operate at said third supply voltage and (ii) generate one or more external output signals in response to said one or more internal output signals.
