ABSTRACT:
A DC translation circuit (200) provides maximum dynamic range in DC level shifting that is temperature and process invariant. The DC translation circuit (200) includes a bandgap reference (202) and current mirror circuit (204) for providing a reference current, Iref. An op-amp circuit (210) receives an AC signal centered about a first DC level, and translates the first DC level into a second DC level using the reference current, a current mirror circuit (208), op-amp circuit (210) and resistor (R2).
