12-Bit ADC IP for GLOBALFOUNDRIES

The WEAADC12BHSI22G is a 12-bit time interleaved Successive Approximation Analog-toDigital Converter (ADC) that supports both singleended and differential operation, depending on the input and reference connections
It integrates 13 WEAADC12BHS22G with programmable clock skew (50ps coarse 4ps fine with minimum step 0.25ps) and pre/post-calibration logic on each
Operating on a 0.8 V power supply, the WEAADC12BHSI22G can provide output up to 2GSPS in 13-interleaved mode
The ADC can be clocked with 2GHz clock

The WEAADC12BHS22G is a 12-bit Successive Approximation Analog-to-Digital Converter (ADC) that supports both single-ended and differential operation, depending on the input and reference connections
It integrates a split-capacitor DAC with a built-in track-and-hold circuit, a dynamic comparator with DC-offset autocalibration, SAR logic state machine, and pre/post-calibration logic
The device also includes gain and offset calibration mechanisms
Operating on a 0.8 V power supply, the WEAADC12BHS22G requires 13 clock cycles for conversion, in 12-bit resolution mode, with digital data available at the rising edge of the 14th clock pulse

The agileADC 12 Analog-to-Digital Converter is a traditional Charge-Redistribution SAR ADC that is referenced to VDD, VSS. The architecture can achieve up to 12-bit resolution at sample rates up to 64 MSPS. It includes a 16-channel input multiplexor that can be configured to be buffered or unbuffered, and support differential or single-ended inputs.

The analog-to-digital converter is a differential high speed low power IP which uses Successive Approximation Register (SAR) architecture to achieve 12-bit resolution.
The ADC includes a core internal SAR ADC which consists of sample/hold circuits, a capacitive DAC, a comparator and logic control circuits.
The ADC is designed with high dynamic performance for input signal frequencies up to Nyquist.
It is perfectly suitable for broadband communication applications.
