ABSTRACT:
A pull-down circuit in a sense amplifier, such a sense amplifier in a memory integrated circuit, includes a pull-down transistor having a drain coupled to a common node, a gate, and a source coupled to ground. An inverter provides a gate control signal to the gate of the pull-down transistor. A choke transistor has a drain coupled to a power terminal of the inverter, a gate, and source coupled to the power supply voltage. A regressive drive bias circuit is coupled to the gate of the choke transistor and provides a relatively low voltage to the gate of the choke transistor at relatively low power supply voltages resulting in a relatively large gate-to-source voltage on the choke transistor and provides a relatively high voltage to the gate of the choke transistor at relatively high power supply voltages resulting in a relatively small gate-to-source voltage on the choke transistor.
