Abstract
In a circuit to convert a first logic signal having a first range to a second logic signal having a second range, a switch selectively couples an output node to a first reference voltage when the output node is to be in a first state based on the control signal. A source-follower circuit having a current source establishes a second reference voltage. A logic circuit coupled to the switch and the source-follower circuit and having a logic gate selectively discharges, in accordance with the control signal, the output node to the second reference voltage when the output node is to transition from the first state to a second state.
