Welcome to City Semiconductor!
We are an analog and mixed-signal IC design house providing world-class intellectual property for the highest-speed applications. Our specialty is circuits that operate in the Gigahertz (GHz) range, including Gigasample-per-second (GSPS) analog-to-digital converters (ADC) and digital-to-analog converters (DAC).
Our high-speed CMOS products find use in a wide range of consumer, industrial, and defense applications, including: Wireless networking, cable and satellite set top boxes, software defined radio, test & measurement, radar, and lidar.
We also provide ultra-high-speed custom and semi-custom design and layout services, and support all aspects of full-volume production for standalone products or complex System-on-Chip ASICs.
