    摘要： A pipelined A/D converter circuit includes a sample hold circuit configured to sample and hold an analog input signal, and output a sample hold signal, and an A/D converter circuit including A/D converter circuit parts connected to each other in cascade, and performs A/D conversion in a pipelined form. The pipelined A/D converter circuit part of each stage includes a sub-A/D converter circuit, a multiplier D/A converter circuit, and a precharge circuit. The sub-A/D converter circuit includes comparators, and A/D convert the input signal into a digital signal of predetermined bits, a multiplier D/A converter circuit for D/A converting the digital signal from the sub-A/D converter circuit into an analog control signal generated with a reference voltage served as a reference value, sample, hold and amplify the input signal by sampling capacitors based on the analog control signal.

    摘要： To improve resolution of a built-in A/D converter by reducing the area occupied by a chip of the built-in A/D converter in a semiconductor integrated circuit that is mounted in an on-vehicle millimeter wave radar device and which incorporates an A/D converter and an MPU. In the semiconductor integrated circuit, a plurality of reception signals of the radar device is A/D-converted by a single digital correction type A/D converter. The digital correction type A/D converter of the single A/D converter is a foreground digital correction type A/D converter that sequentially A/D-converts the reception signals output from a multiplexer of a receiving interface. The single A/D converter includes a pipeline type A/D converter having a plurality of cascade-coupled converters. The semiconductor integrated circuit comprises a correction signal generating unit, a digital correction D/A converter, and a digital correction unit for digital correction.
