摘要： An analog multiplexer core circuit (120A) includes a differential pair (121) that includes two transistors (Q1, Q2), a differential pair (122) that includes two transistors (Q3, Q4), a differential pair (123) that includes two transistors (Q5, Q6), and a constant current source (124) that causes a current (I EE ) to flow. This analog multiplexer core circuit (120A) time-multiplexes two analog signals (Ain1, Ain2) and outputs a time-multiplexed analog signal (Aout). Each emitter resistor (R EA 1, R EA 2, R EA 3, R EA 4) is connected to a corresponding one of the transistors (Q1, Q2, Q3, Q4). At this time, a relation of "R EA ·I EE ≥ the amplitude of an input analog signal" is satisfied. As a result, linearity of response can be ensured by expanding the linear response input range of the differential pairs (121, 122).

摘要： A vector sum phase shifter includes a 90° phase shifter (1) which generates an in-phase signal (VINI) and a quadrature signal (VINQ) from an input signal (VIN), a four-quadrant multiplier (2I) which changes the amplitude of the in-phase signal (VINI) based on a control signal (CI), a four-quadrant multiplier (2Q) which changes the amplitude of the quadrature signal (VINQ) based on a control signal (CQ), a combiner (3) which combines the in-phase signal (VINI) and the quadrature signal (VINQ), and a control circuit (4). The control circuit (4) includes a voltage generator which generates a reference voltage, and a differential amplifier which outputs the difference signal between a control voltage (VC) and the reference voltage as the control signal (CI, CQ). The differential amplifier performs an analog operation of converting the control voltage (VC) into the control signal (CI, CQ) similar to a sine wave or a cosine wave.
