Abstract
The system converts output signals from the conventional circuit into input signals configured for the ULP circuit. This system preferably scales down the output signals from the conventional circuit to allow the ULP circuit to receive these signals as corresponding input signals without damaging the ULP circuit. Further, the system also converts output signals from the ULP circuit into input signals configured for the conventional circuit. This system preferably increases the voltage level and voltage swing of the output signals from the ULP circuit to be compatible as corresponding input signals for the conventional circuit. The system is a circuit formed in a semiconductor substrate having improved immunity to total ionizing dose radiation. By back-biasing the n-type material and the p-type material, the effective threshold voltages of the transistors both drawn and parasitic are preferably dynamically tuned. Preferably, by optimizing the threshold voltages of the n-channel and p-channel transistors, the total ionizing dose radiation effect is neutralized and lower supply voltages are utilized for the circuit which would result in the circuit requiring less power.
