IP Cores

12 bit SAR ADC

The GF Micro ADC is a low power, 12-bit, successive approximation (SAR) Analogue-to-Digital Convertor (ADC) in the form of an IP block. The ADC mainly comprises a Capacitive Digital to Analog Converter (CDAC), a dynamic comparator, and an asynchronous SAR control logic.


Being compact and low power, it is designed specifically for battery powered systems. The sampling rate is 500 KSPS and both differential nonlinearity (DNL) and integral nonlinearity (INL) are < 2 LSB.


The IP block is designed in TSMC 40nm CMOS technology but can be retargeted to other processes and temperature ranges, allowing it to be used in design applications as diverse as biomedical imaging, industrial process control and high speed communication systems.

Digital temperature sensor

Perfectly suited for industrial applications, the GF Micro digital temperature sensor is available as a Licensed IP block.


It uses a low power 1.8V supply and has an operating range of -40°C to 125°C with an accuracy of ±1°C. Calibration points are conveniently placed at 25°C and 125°C – temperatures typically used for production test and wafer probe. The sensor produces a digital value accessible from a register location. Industry-standard digital interfaces are supported for easy product integration.


The IP has been developed using the Global Foundries 28SLP process and has a 273μm x 292μm footprint. It can also be re-targeted to other process nodes, making it a very flexible piece of IP for any design where space is at a premium.
