摘要： A digital clock modulator provides a smoothly modulated clock period to reduce emitted electro-magnetic radiation (EMR). The digital clock modulator includes a plurality of delay elements connected in series and receiving as an input an unmodulated clock signal. A multiplexer receives inputs from unequally spaced taps between the delay elements. A control block provides selection inputs to the multiplexer, and receives the unmodulated clock signal from the delay elements. The delay elements include a last delay element providing the unmodulated clock signal to the control block. The last delay element has a predetermined delay for ensuring that the delay elements and related signal paths are in a same stable state before control to the multiplexer changes.

摘要： A supply identifier takes precise decision on the range of the external supply to manage a proper internal supply to the core of the IC by controlling a regulator or a switch connected to external supply. This supply identifier defers the decision until everything that influences the decision settles after power-up, then makes a decision only once depending on the external supply range and switches itself off, keeping the decision stored, to avoid noise-induced wrong behavior and to reduce power consumption.

摘要： A circuit includes a differential amplifier having a folded cascode architecture with a pair of cascode transistors. A sensing circuit senses a common mode input voltage of a differential input signal applied to the differential amplifier. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. The bias generator circuit is connected to an output of the sensing circuit such that the generated bias voltage has a value which is dependent on the sensed common mode input voltage. This dependence stabilizes a common mode output voltage from the differential amplifier in response to changes in the common mode input voltage.

摘要： Described herein are various principles for operating a transmitter circuit to reduce noise affecting a signal being generated and reducing jitter. In some embodiments, a circuit is operated in a way that switching occurs at or above a bit rate of transmission, such that at least one switch changes state at least for every bit. Operating the circuit in such a way leads to a switching rate that is above a resonant frequency of the circuit and prevents large oscillations and noise from being inserted into the signal and causing communication problems.
