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 has a source coupled to the output node and a gate
coupled to a bias voltage. A current source circuit selectively biases
the second MOS transistor to act as part of a source-follower circuit
when the output node is to be in a second state. Additionally, a memory
circuit has an input coupled to the output node, and an output. The
memory circuit is configured to temporarily store a Boolean value of the
output node when the output node transitions from the first state to the
second state. Further, a discharging circuit is coupled to the output
node and a second reference voltage. The discharging circuit is
configured to temporarily provide a discharging path between the output
node and the second reference voltage when the output node is
transitioning from the first state to the second state. The discharging
circuit has a first input coupled to the output of the memory circuit and
a second input coupled to a control signal. The control signal indicates
that the output node is to transition from the first state to the second
state.
