Semiconductor device, and operating device, signal converter, and signal processing system using the semiconductor device

摘要

A reduction in circuit size, an increase in operation speed, and a reduction in power consumption can be attained by a semiconductor device, in which capacitors (202) are connected to multiple input terminals (IN-1 to IN-n) through switch (203), one terminal (b) of each capacitor is commonly connected, and the common connection terminal is connected to a sense amplifier (205), including a reset (207) at a floating point which is the contact (b) between the common connection terminal of the capacitors and the input of the sense amplifier. In addition, an increase in yield can be realized by reducing the manufacturing cost.
