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 transistor selectively couples an output node to a first reference voltage when the output node is to be in a first state. A second transistor selectively discharges the output node toward a second reference voltage via a resistor when the output node is to transition from the first state to a second state, the second state being a logical complement of the first state. A source-follower circuit has a source follower output coupled to the output node and has a dynamic current source, the dynamic current source having a control input coupled to the resistor. A third transistor selectively couples the source follower output to the dynamic current source when the output node is to be in the second state.
