Classification of Callibration Techniques Calibration comprises two phases – Error estimation – Error correction Analog approach additional analog components, noise, power, distortion, etc. Digital approach: Works on reults only, i.e. does not interfere with analog signal processing Calibration Foreground Background Stephan Henzler Mixed-Signal-Electronics 2012/13 Virtual True Ginés et al., A Survey on Digital Background Calibration of ADCs, ECCTD, 2009. 224
Summary Pipeline ADC Stage errors can be tolerated if the residue stays inside the convergence region – Minimum requirement is that the residue is back in the convergence region before the final quantizer) – Take care for nonlinearity which is not revealed by the linear model Trade-off sampling frequency – resolution – latency Number of stages, i.e. number of elements grows linearly with resolution (not exponentially, ref flash ADC) Accurate sample-and-hold elements required (That’s the reason why pipelined time-to-digital converters do not exist) Stephan Henzler Mixed-Signal-Electronics 2012/13 225
