Abstract

A Hall sensor trim circuit includes a current source, a transistor, a reference voltage circuit, an amplifier, and a Hall sensor. The transistor includes a first terminal, a second terminal, and a third terminal. The third terminal is coupled to the current source. The amplifier includes an output terminal, a first input terminal, and a second input terminal. The output terminal is coupled to the first terminal of the transistor. The first input terminal is coupled to the second terminal of the transistor. The second input terminal is coupled to the reference voltage circuit. The Hall sensor is coupled to the current source.
