Abstract: A wide-band single-ended-to-differential low-noise amplifier using a push-pull architecture with an input node coupled to the sources of a first PMOS transistor and a first NMOS transistor, a positive output node coupled to the drains of the first PMOS transistor and the first NMOS transistor, a negative output node coupled to the drains of a second PMOS transistor and a second NMOS transistor, and bias circuitry coupled to the gates of the first and second PMOS and first and second NMOS transistors. The source of the first PMOS transistor is coupled to the gate of the second PMOS transistor, the source of the first NMOS transistor is coupled to the gate of the second NMOS transistor, the source of the second PMOS transistor is coupled to a first supply voltage, and the source of the second NMOS transistor is coupled to a second supply voltage.
