摘要： Clock and data regenerator with demultiplexer function wherein the clock and phase generator operates with four sampling flip-flops whose output signals are compared with one another with the aid of two pairs of EXOR elements. The associated phase signals generated by the EXOR elements are added and compared with one another. The phase regulating voltage thus obtained controls an oscillator which generates the sampling clock signals.

摘要： An asymmetrical differential amplifier as a level converter has two transistors, a constant current source and two resistors, whereby the first transistor is a MOS transistor and the second transistor is a bipolar npn transistor. Input signals having CMOS level can be applied to an input on the input side of the differential amplifier, whereas output signals having ECL level can be taken at an output. In addition to being a differential amplifier, the circuit also produces a level conversion between CMOS level at the input side and ECL level at the output side.

摘要： An RFID transponder comprises an antenna for receiving data in a downlink mode and transmitting data in an uplink mode, with a modulation stage for modulating uplink data and a demodulation stage for demodulating downlink data. A class C amplifier is provided, which has a resonant circuit, a plucking device coupled to the resonant circuit, and a controllable pulse width generator coupled to the plucking device. The controllable pulse width generator is adapted to periodically switch the plucking device on and off so as to maintain an oscillation of the resonant circuit. The transponder further comprises a phase locked loop configured to be locked to an oscillating signal received through the antenna and to be switched into a free running mode without being locked to the oscillating signal received through the antenna, thereby being adapted to output an independent internal clock signal for the RFID transponder.

摘要： An ECL-CMOS converter composed of a voltage-to-current converter and of a current-to-voltage converter is interconnected according to the "mismatched amplifier" principle. At two inputs of the voltage-to-current converter, the ECL input voltages are converted into a current that can be taken at an output of the voltage-to-current converter. The current is subsequently amplified in a current-to-voltage converter to an output voltage that is available at an output of the current-to-voltage converter. The current-to-voltage converter is composed of a feedback inverter stage, as a result thereof the operating point at an input of the current-to-voltage converter is stabilized at about half of an operating voltage of the converter.

摘要： An RFID transponder is provided which includes an automatic gain control (AGC) stage for amplifying a radio frequency (RF) signal and for providing an amplified RF signal. The AGC stage has a control signal indicating an increase of the amplitude of the RF signal. A demodulator is coupled to receive the amplified RF signal for demodulating the amplified RF signal. The demodulator provides a data signal. A burst detector is coupled to receive the control signal of the AGC stage and adapted to provide a start signal in response to a change of the control signal. A wake pattern detector is coupled to receive the data signal and the start signal. The wake pattern detector is adapted to detect a predefined wake pattern in the data signal after having received the start signal and to issue a wake signal if the predefined wake pattern is detected for switching the RFID transponder from a first operating mode into a second operating mode having higher power consumption than the first operating mode.

摘要： An adder cell having a sum part and a carry part, whereby the sum part and the carry part each contain differential amplifiers having exclusively bipolar or ECL technology as well as differential amplifiers having mixed bipolar MOS transistors. The processing speed can be considerably increased with such an arrangement in comparison to exclusive CMOS adder cells. Additionally, the adder cell carries out a level conversion of CMOS input levels to ECL output levels, so that CMOS levels between 0 and 5 volts can be received at the first four inputs (E1, E2, E3, E4) and ECL boosts in the millivolt range can be taken at the sum outputs (S, S) or, at the carry outputs (CO, CO).
