An electronic device comprises one or more functional units, each functional unit being clocked by a respective clock signal. The electronic device further comprises a monitoring unit for providing a real-time estimate of an electrical current consumed by the functional units. The monitoring unit provides the real-time estimate on the basis of characteristic signals. The characteristic signals may comprise one or more of said clock signals, or one or more clock generating signals used to generate said clock signals. The electronic device may further comprise a power regulator responsive to the real-time estimate. A method of estimating in real-time an electrical current consumed by one or more functional units is also described.

Electronic device and method

Embodiments of the present invention provide a voltage level shifter used to translate a binary input signal representing a binary sequence to a binary output signal representing the same binary sequence. The input signal is provided by an input voltage varying between a first input voltage level and a second input voltage level. The output signal is provided by an output voltage varying between a first output voltage level and a second output voltage level. The output signal has a delay relative to the input signal, and the voltage level shifter has a leakage current. The voltage level shifter has a first operating mode and a second operating mode. In the second operating mode, the delay is shorter while the leakage current is higher than in the first operating mode.

Voltage level shifter having a first operating mode and a second operating mode

An integrated circuit, comprises a power supply node being connectable to a voltage supply (Vdd); a ground node connectable to ground (GND); and an electrostatic discharge protection structure for diverting an electrostatic discharge away from protected parts of the integrated circuit. A gated domain is present which is supply gated and/or ground gated with respect to the power supply node and/or the ground node, as well as a gating switch for gating the gated domain relative to the power supply node and/or the ground node. The gating switch enables in a connecting state, and in a disconnecting state inhibits, an electrical connection between the gated domain and at least one of: the power supply node and the ground node. The integrated circuit includes ESD gating control circuitry for controlling in case of an electrostatic discharge event the gated domain to be electrically connected to the power supply node and/or the ground node.
