摘要： According to one embodiment, a first switch transistor and a second switch transistor convert an input current to a first current and a second current by performing a switching operation on the basis of differential input voltages, respectively. An input current source supplies the input current to the first and second switch transistors. A noise current generating circuit generates a dummy current to simulate a noise current flowing through the input current source. A third switch transistor and a fourth switch transistor convert the dummy current to a third current and a fourth current by performing a switching operation on the basis of differential input voltages and negatively superimposes the third current and the fourth current on the first and second currents, respectively.

摘要： First and second resistor series divide a predetermined voltage range to generate first reference voltages and second reference voltages, respectively. First and second switch controlling circuits select respective ones of the first reference voltages and the second reference voltages. A comparing unit generates a logical signal representing a logical value by comparing a combined transistor current based on the selected first and second reference voltages with a transistor current based on an input signal. The first switch controlling circuit specifies two adjacent first reference voltages where the logical value is inverted by sequentially selecting the first reference voltages, and determines to select one of the adjacent reference voltages. Te second switch controlling circuit specifies two adjacent second reference voltages where the logical value is inverted by sequentially selecting the second reference voltages, and determines to select one of the adjacent reference voltages.
