摘要： In an architecture for processing data comprising a control unit and converters CNj to be synchronized to an active front of a common reference clock CLK, the synchronizing method makes provision for the converters to be arranged in at least one series chain, and for a procedure for synchronizing the converters by propagating a synchronizing signal SYNC-m emitted by the control unit, said signal being retransmitted as output OUT by each converter, after resynchronization to a clock active front, to a synchronization input IN of a following converter in the chain. Each converter comprises a synchronization configuration register REG containing at least one polarity parameter Sel-edgej that sets the polarity of the reference-clock front for reliable detection of a synchronizing signal received via the input of the converter. A phase parameter Sel-shiftj furthermore allows the phase of the sampling clocks of n converting cores of the converters, working at a sampling frequency obtained by dividing by n the CLK reference-clock frequency, to be synchronized.

摘要： An integrated constant time delay circuit utilized in continuous-time (CT) analog-to-digital converters (ADCs) can be implemented with an RC lattice structure to provide, e.g., a passive all-pass lattice filter. Additional poles created by decoupling capacitors can be used to provide a low-pass filtering effect in some embodiments. A Resistor-Capacitor “RC” lattice structure can be an alternative to a constant-resistance Inductor-Capacitor “LC” lattice implementation. ADC architectures benefit from the RC implementation, due to its ease of impedance scaling and smaller area.
