Abstract: Proposed are a seat side bolster apparatus and a control method thereof. The seat side bolster apparatus of the disclosure includes a driving unit, which is provided under a foam pad of a seat cushion, is moved upwards and downwards by operation of an actuator, and presses the foam pad upwards when moving upwards, and a covering bracket, which is connected to the driving unit so as to be moved upwards and downwards together with the driving unit and to which an end of a covering enveloping the foam pad of the seat cushion is fixed.

Abstract: An analog to digital converter includes a digital to analog converting circuit, a comparator and a signal processing circuit. The digital to analog converting circuit samples and holds an analog input signal, and converts digital output data to an analog signal to generate a hold voltage signal. The comparator compares the hold voltage signal with a reference voltage signal in response to a rising edge and a falling edge of a clock signal to generate a comparison output voltage signal. The signal processing circuit performs successive approximation based on the comparison output voltage signal to generate the digital output data.

Abstract: An electronic device, such as a sample-and-hold circuit, includes a field effect transistor (FET), a capacitor, and a voltage offset circuit. The FET is configured to receive a signal at a first terminal thereof and selectively provide the signal to a second terminal thereof responsive to a switching signal at a gate terminal thereof. The capacitor is electrically connected to the second terminal of the FET. The voltage offset circuit is electrically connected to the first terminal and the gate terminal of the FET. The voltage offset circuit is configured to maintain a substantially constant voltage differential between the first terminal and the gate terminal of the FET while the signal is provided to the second terminal of the FET and substantially independent of a voltage level of an input signal. Related methods of operation are also discussed.
