Claim 1:
2. The semiconductor device according to claim 1, wherein
the reference voltage circuit comprises: a control terminal; a memory circuit comprising an output port outputting an adjustment code signal of N bits taking a natural number N as an adjustment bit number; a decoder which comprises an output port outputting a current control signal and generates the current control signal according to the adjustment code signal and the control signal received at the control terminal of the reference voltage circuit; a first variable current source; a second variable current source; a reference common mode voltage terminal; an output terminal; and a resistor comprising a first port connected to the reference common mode voltage terminal, and a second port connected to the output terminal, wherein
the first variable current source comprises a first port receiving the current control signal, and a second port connected to the output terminal, wherein based on the current control signal containing a first logic or a second logic, an output current value is controlled to zero in response to receiving the current control signal which is the first logic, and the output current value is controlled to a current value based on the adjustment code signal in response to receiving the current control signal which is the second logic, and
the second variable current source comprises a first port receiving the current control signal containing a first logic or a second logic, and a second port connected to the output terminal, wherein based on the current control signal, an output current value is controlled to a current value based on the adjustment code signal in response to receiving the current control signal which is the first logic, and the output current value is controlled to zero in response to receiving the current control signal which is the second logic.
