摘要： The inventive concepts relate to variable gain amplifiers. The variable gain amplifier including an amplifier, a first fixed resistor and a first variable resistor, a second fixed resistor and a second variable resistor, a third fixed resistor and a third variable resistor, a fourth fixed resistor and a fourth variable resistor, a first output terminal and a second output terminal, and a decoder may be provided. The decoder is configured to receive first control bits, generate second control bits from the first control bits, generate third and fourth control bits from the first or second control bits, respectively, transmit the first control bits and the third control bits to the third and fourth variable resistors to adjust resistance values, and transmit the second and fourth control bits to first and second variable resistors to adjust resistance values.
