摘要： An analogue-to-digital converter for converting an analogue input signal into a digital output signal, the analogue-to-digital converter including two conversion paths, each configured to receive a version of the analogue input signal and convert it into a digital bit stream, a first feedback loop configured to provide feed-back, to both paths, that is indicative of a difference between the digital bit streams output by the two paths, and a second feedback loop configured to feed-back, to both paths, that is indicative of an average of the digital bit streams output by the two paths.

摘要： A transimpedance amplifier includes a current regulator having a first current mirror of a first conduction type and a first current mirror of a second conduction type. The first current mirror stage of a first conduction type receives a reference current. The first current mirror stage of a second conduction type is connected to the first current mirror stage of the first conduction type, and receives an output current from the first current mirror stage of the first conduction type, and to generate a current to be used as a current source by a transimpedance amplifier. Each of the current mirror stages includes a first transistor and a second transistor of the same conduction type having their gate terminals connected wherein the first transistor receives an input current and the second transistor provides an output current that is a factor of the received input current.
