  • Power control in integrated circuits
    Patent number: 10331201
    Abstract: An integrated circuit device comprising a power control unit for controlling the power of a power isle is disclosed. The power control unit comprises (i) a power gating switch implemented in the BEOL portion for switching ON/OFF the power to the power isle, (ii) a state recovery circuit comprising a memory element in the FEOL portion or BEOL portion and a transistor configuration in the BEOL portion, and (iii) a wake-up/sleep circuit in the BEOL portion adapted for receiving an identifier. The wake-up/sleep circuit is operatively connected with the power gating switch and with the state recovery circuit. Responsive to receiving the identifier, the wake-up/sleep circuit causes the power gating switch to switch OFF/ON the supply power to the power isle and causes the state recovery circuit to store/restore the state of the power isle.

  • High speed wireless OFDM transceiver modem
    Patent number: 6760300
    Abstract: An apparatus for receiving and/or transmitting signals using orthogonal frequency division multiplexing, said apparatus being adapted for outputting a first output signal, comprising: a time synchronisation circuit, being adapted for determination of control information from a first signal, said first signal comprising at least of a first part being a non-orthogonal frequency division multiplexing signal and a second part being an orthogonal frequency division multiplexing signal, said determination of control information exploiting said first part of said first signal; said time synchronisation circuit, further being adapted for converting said second part of said first signal into a second signal, being in time domain representation; a transformation circuit at least converting said second signal into a third signal, being in frequency domain representation; a first frequency domain circuit, at least converting said third signal into said first output signal; and said second signal and said second part
