Abstract:
An analog multiplexer core circuit ( 120 A) includes a differential pair ( 121 ) that includes two transistors (Q 1,  Q 2 ), a differential pair ( 122 ) that includes two transistors (Q 3,  Q 4 ), a differential pair ( 123 ) that includes two transistors (Q 5,  Q 6 ), and a constant current source ( 124 ) that causes a current (I EE ) to flow. This analog multiplexer core circuit ( 120 A) time-multiplexes two analog signals (Ain 1,  Ain 2 ) 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 (Q 1,  Q 2,  Q 3,  Q 4 ). 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 ).

Claim (Index 18):
The analog multiplexer circuit according to  claim 17 , wherein the level shifter comprises\n an eleventh transistor that includes a collector connected to the high-potential power supply, a base to which the positive-phase signal of the time-multiplexed analog signal is input, and an emitter, a first constant current source that includes one terminal which is connected to the emitter of the eleventh transistor and the other terminal which is connected to the low-potential power supply, a twelfth transistor that includes a collector connected to the high-potential power supply, a base to which the negative-phase signal of the time-multiplexed analog signal is input, and an emitter, and a second constant current source that includes one terminal which is connected to the emitter of the twelfth transistor and the other terminal which is connected to the low-potential power supply.
