Abstract: A low dropout voltage regulator, coupled to a load circuit receiving a clock signal, includes an amplifier; a power transistor comprising a control terminal, coupled to an output terminal of the amplifier; and a first terminal, coupled to a positive input terminal of the amplifier and the load circuit; and a control circuit, configured to control a current flowing through the power transistor in response to the clock signal.

Abstract: A touch display apparatus having a fan-out side is provided. The touch display apparatus includes a first substrate, a second substrate, a touch sensing element and a display element. The first and the second substrate have a first surface and a second inner surface, respectively. The second substrate is disposed opposite to the first substrate. The second inner surface faces the first inner surface. The second substrate has a convex part and a concave part on the fan-out side. The second inner surface has a second outer lead bonding region in the convex part. The first outer lead bonding region of the first substrate is unshielded by the second substrate through the concave part. The second outer lead bonding region of the second substrate is unshielded by the first substrate. The touch sensing element and the display element are packaged in between the first and the second substrates.

Abstract: An analog-to-digital converting circuit includes a reference circuit and an analog-to-digital converter (ADC). The reference circuit provides a base voltage, which has one end grounded. The ADC receives an analog input signal and a base voltage signal. The ADC includes a first DC buffer and an ADC core unit. The first DC buffer internally receives an offset voltage signal and a data voltage signal to be digitized, and outputs two converting control signals. The ADC core unit receives the two converting control signals from the first DC buffer and an ADC input range voltage signal, and outputs a digital code. All of the offset voltage signal and the data voltage signal and the ADC input range voltage signal have been added with the base voltage signal.
