Abstract
PURPOSE: To carry out a precise sampling by adding the level shift circuit to the floating type analogue switch using sample hold circuit.
CONSTITUTION: To the sample hold circuit, the level shift circuit comprising the fixed voltage generating circuits V1, V2 and impedance converters 51, 52. The switching signal supply source 3 is formed by the pulse transformer having three windings. The windings 42 and 43 are formed so as to excite the reverse direction voltage to each other. In the construction as mentioned above, when input signal is impressed to the terminal 11 of the analogue switch 1, respectively the negative side level shifted input signal is put out to output of the circuit 5 and the positive side level shifted signal is put out as output and the error discharge of the hold capacitor 2 is prevented. Since the amplitude of the pulse of the switching signal of the switch is constant, error in the switching time is not found and the precise sampling can be done.
