An amplifier circuit can include a first supply terminal to receive a first reference voltage; a second supply terminal to receive a second reference voltage; a first pair of circuit paths extending between the first and second supply terminals and including a respective output terminal, the first pair of circuit paths including a first pair of transistors, each having a gate connected to a respective one of the input terminals and a source connected to the first supply terminal, and a second pair of transistors, each having a gate connected via a first impedance to a gate of a respective first transistor, and a source coupled to the second supply terminal. The amplifier circuit can also include a second pair of circuit paths extending between the first and second supply terminals, the second pair of circuit paths including a third pair of transistors, each having a gate connected to one of the input terminals, and a source connected to the first supply terminal, and a fourth pair of transistors, each having a source connected to the second supply terminal, and a gate connected via a second impedance to a gate of a second transistor from a respective first circuit path.
