This pipelined ADC can be applied for up to 20MSps sampling frequencies. By using
interleaved switched-capacitor circuitries a CLK signal with half the sampling rate needs to be applied.
This ADC is built as a single-ended architecture and is designed to convert input signals from 0.5 – 2.3V at 3.3V supply voltage with up to 10 MHz input bandwidth with 12 bits resolution.
The ADC IP includes reference voltage generation with buffers and optional high-precision bandgap reference. The accuracy of the ADC is ensured by one-time-trimming of the reference voltages. Power-down mode is available.
The ADC is silicon proven using the XFAB XH035 process. Measurement results and samples are available.
