摘要： A system for register error detection is described, the system comprising: a plurality of addressable registers comprising sets of registers, the registers in each set having contiguous addresses; a cyclic redundancy check generator coupled to the addressable registers and configured to determine a cyclic-redundancy-check result for each set of registers from the values of each of the respective set of registers; a controller coupled to the registers and the cyclic-redundancy-check generator. The controller comprises a cyclic-redundancy-check calculator and is configured to determine an expected cyclic-redundancy-check result from expected values for each of the set of registers, to read the cyclic-redundancy-check result for each of the set of registers determined by the cyclic-redundancy-check generator, and to compare the generated cyclic-redundancy-check result with the calculated cyclic-redundancy-check result and wherein a difference between the generated cyclic-redundancy-check result and the calculated cyclic-redundancy-check result is indicative of an error condition.

摘要： A charge pump driver circuit comprises an output stage and a current generator component. The output stage is arranged to receive at an input node thereof a control current signal and comprises a resistance network coupled between the input node thereof and a reference voltage node and arranged to provide a resistive path through which the control current signal flows. The output stage is arranged to generate at an output node thereof a charge pump control voltage signal based on the voltage level at the input node thereof The current generator component is arranged to receive an indication of a voltage level of a charge pump output signal, and to generate a feedback current dependent on the voltage level of the output signal, wherein the feedback current is injected into the resistive path of the resistance network through which the control current signal flows.
