Semiconductor device and electronic device including the semiconductor device

A semiconductor device comprising:

• a shift register;
• a sample-and-hold circuit;
• a first demultiplexer;
• a second demultiplexer;
• a first buffer circuit;
• and
• a second buffer circuit,
• wherein the sample-and-hold circuit comprises a first input terminal, a second input terminal, and an output terminal,
• wherein an output terminal of the first buffer circuit is electrically connected to the first input terminal of the sample-and-hold circuit,
• wherein the shift register is electrically connected to the second input terminal of the sample-and-hold circuit,
• wherein an input terminal of the second buffer circuit is electrically connected to the output terminal of the sample-and-hold circuit,
• wherein the first demultiplexer is electrically connected to the output terminal of the first buffer circuit and the first input terminal of the sample-and-hold circuit,
• wherein the second demultiplexer is electrically connected to the shift register and the second input terminal of the sample-and-hold circuit,
• wherein an input terminal of the first buffer circuit is configured to receive an analog signal, and
• wherein the sample-and-hold circuit is configured to receive the analog signal through the first input terminal when a signal from the shift register is transmitted to the second input terminal and is configured to hold a potential corresponding to the analog signal.
