Abstract
In a circuit to convert a first logic signal having a first range to a second logic signal having a second range, a first metal oxide semiconductor (MOS) transistor selectively couples an output node to a first reference voltage when the output node is to be in a first state. A second MOS transistor selectively discharges the output node toward a second reference voltage when the output node is to transition from the first state to a second state, the second state a logical complement of the first state. An output of a source-follower circuit, having a current source, is coupled to the output node. A third MOS transistor selectively couples the current source of the source-follower circuit to the second reference voltage when the output node is to be in the second state.
