    Abstract: An example apparatus includes: a differential amplifier including: an inverting input coupled to a first input via a first resistor; a non-inverting input coupled to a second input via a second resistor; a first supply input coupled to the first input via a third resistor, and the first supply input coupled to the second input via a fourth resistor; a second supply input coupled to a current source; a non-inverting output; and an inverting output; a first transistor including a first control terminal and a first current terminal, the first control terminal coupled to the non-inverting output and the first current terminal coupled to the inverting input; and a second transistor including a second control terminal and a second current terminal, the second control terminal coupled to the inverting output and the second current terminal coupled to the non-inverting input.
