Abstract
A circuit includes a first transistor of a first type, a second transistor of a second type, a sense amplifier, a first data line, and a second data line. The second type is different from the first type. The first data line is coupled with a first terminal of the sense amplifier. The second data line is coupled with a second terminal of the sense amplifier. A first terminal of the first transistor is configured to receive a supply voltage. A second terminal of the first transistor, a third terminal of the first transistor, a second terminal of the second transistor, a third terminal of the second transistor are coupled together and are configured to carry a voltage. A first terminal of the second transistor is configured to receive a reference supply voltage. The first and second data lines are configured to receive a voltage value of the voltage.
