Abstract
A sense amplifier that is capable of sensing small differential voltage between two inputs with full voltage range includes a first inverter 305 and 306; a second inverter 307 and 308 cross coupled with the first inverter; a first transmission gate 301 coupled between a reference node REF and an input of the first inverter; a second transmission gate 302 coupled between a data node RD and an input of the second inverter; a pull-up enable switch 303 coupled between a high side voltage source node VDD, and the first and second inverters; and a pull-down enable switch 304 coupled between a low side voltage source node, and the first and second inverters.
