An integrated circuit includes functional blocks, a power control unit controlling the provision of power to the different functional blocks of the integrated circuit, a detecting unit detecting if a turned off functional block is to be turned on, and a clock signal control unit controlling the provision of the clock signal for the functional blocks. The clock signal control unit interrupts the clock signal for the activated functional blocks of the integrated circuit for a predetermined number of clock cycles. The power control unit provides power to the turned off functional block during the interrupted clock cycles.

A method and an apparatus for switching on a voltage supply of a voltage domain of a semiconductor circuit is disclosed. A voltage supply is connected to a supply voltage of the semiconductor circuit by means of a switchable element. The switchable element is activated in such a way that, for switching on the voltage supply of the voltage domain, a current through the switchable element rises progressively with at least one intermediate value, in particular stepwise manner.

A master latch circuit (10) with signal level displacement for a flip-flop (1) clocked by a clock pulse signal (Clk), wherein the master latch circuit (10) comprises a signal delay circuit (13) which delays and inverts the clock pulse signal (ClK) resulting in a specific time delay (AT), and a circuit node (14) which, in a charging phase wherein the clock pulse signal (Clk) is logically low, is charged to an operational voltage (VB) an which, in an evaluation phase when the clock pulse signal (Clk) and delayed, inverted clock pulse signal (Clk DELAY ) are logically high, is discharged according to a specific data signal (D), wherein the data signal controls only transistors of a single type (either only N-channel or only P-channel). The master latch circuit (10) has only one supply voltage.
