Design Considerations for Stochastic Analog-to-Digital Conversion

Using knowledge of the random nature of device mismatch it is possible to employ stochastic techniques in an ADC. This would allow the use of many smaller and less accurate components, and may make it possible to save power and area while maintaining accuracy. Additional benefits include high scalability and high yield with process variation. Various design considerations are suggested that must be addressed to design a successful stochastic ADC and an example calibration and decoding scheme is described.
