ABSTRACT:
A configurable voltage bias circuit is used to control gate delays in buffers by adjusting the supply voltage of the buffers. The programmable voltage bias circuit includes a configurable voltage divider, which receives an input supply voltage and generates an output supply voltage, and a configurable resistance circuit, which is coupled between the configurable voltage divider and ground. By using a temperature dependent reference voltage to generate the input supply voltage, the output supply voltage is also made to be dependent upon temperature. The programmable voltage bias circuit of the present invention uses the temperature dependence of the output supply voltage to make the gate delays of the buffer temperature-independent.
