SAMPLE AND HOLD AMPLIFIER FOR DECREASING CHARGE INJECTION IN INTERIOR DEVICE
摘要
PURPOSE: An SHA (Sample and Hold Amplifier) for suppressing charge outflow at an internal device is provided to prevent the operation distortion of the SHA by suppressing the charge outflow at a switch which delivers an input signal to a charging device. CONSTITUTION: A switching unit (110) includes a plurality of switches (MN1-7, MP1-3), an inverter (I) and a capacitor (C1). The switching unit delivers an input signal to a charging unit. The charging unit charges the input signal delivered through the switching unit. A charge outflow suppressing unit (130) includes a micro-inductor (ML). The charge outflow suppressing unit suppresses the charge outflow at the switching unit.
