    摘要： In accordance with an embodiment of the invention there is provided a sample and hold demodulator circuit (200) for use in an automotive immobilizer to recover modulation information from a received modulated carrier signal (VRD). Sample and hold circuitry samples signals to recover the modulation information therein, and control circuitry (214) is coupled to the sample and hold circuitry for controlling operation thereof. The control circuitry includes shift register circuitry (252) for receiving a second received signal having a same frequency as a carrier frequency of the received modulated carrier signal and for producing at its outputs signals (SAMPLE, SAMPLE2, LATCH) for controlling operation of the sample and hold circuitry. The sample and hold demodulator circuit provides a single IC solution, allowing amplitude and phase demodulation to be performed with a single sample and hold circuit.

    摘要： An integrated circuit comprises a frequency detector. The frequency detector comprises a timer state machine unit operably couplable to a timer and arranged to receive an incoming carrier signal; determine whether the incoming carrier signal comprises a valid frequency; generate a valid carrier indication when the incoming carrier signal is determined as having a valid frequency; and adjust the timer between at least a first timing mode of operation and a second timing mode of operation of the frequency detector in response to the determination.

    摘要： A wake-up control system comprises a plurality of different signal analyzer units. The plurality of different signal analyzer units may process a value of a different parameter of an incoming signal received at an input of a receiver and provide a false wake-up indication for the parameter when the value of the parameter is outside an acceptance range for the value. The system further comprises an evaluation unit connected to the plurality of different signal analyzer units for receiving the false wake-up indications. The evaluation unit may provide a false wake-up parameter information identifying an identified parameter of the different parameters when a sum of the false wake-up indications is outside an occurrence range for the false wake-up indications for the identified parameter.

    摘要： Versatility and flexibility of integrated circuits can be accomplished by remote control via a serial interface, such as SPI. Read/write accesses to the SPI slave node can be achieved according to SPI protocol by the master node. Additionally, a state machine associated to the slave node SPI needs a local clock to exercise the control of the analog functions following a write access. The serial protocol defines a serial data word transfer to comprise a number of reserved clock cycles that are not assigned for communicating a data bit value of the data word. The slave device comprises a clock unit coupled to the serial clock line for providing a derived clock based on reserved clock cycles. The derived clock is used internally in the slave device to perform internal synchronous operations.
