摘要: The phase locked loop (PLL) with adjustable phase shift is described. The PLL includes a voltage controlled oscillator which is capable of generating multiple phase shifted output signals, and multiple phase detectors capable of determining the phase differences between the output signals and a reference clock. The PLL further includes a weighting device capable of weighting the phase differences and generating a control signal for the voltage controlled oscillator.

摘要: The present invention provides integrated line drivers useable for driving data signals with high data rates wherein the area consumption of the line driver is minimized and wherein the influence of electrostatic discharge devices and process tolerances are minimized too. An example of an integrated line driver according to the invention comprises a first driver stage followed by a second driver stage, and a feedback unit forming with the second driver stage a control loop. The integrated line drivers are useable for driving data signals with high data rates wherein the area consumption of the line driver is minimized and wherein the influence of ESD devices and process tolerances are minimized. Advantageously, the integrated line driver according to the invention complies with chip design methodologies, where 10 or more routing metal layers are used.

摘要: The apparatus for transmitting and receiving data according to the invention contains a transmitter (1) for serial data transmission and a receiver (3) for receiving a transmitted data signal (g(t)). The receiver (3) in turn comprises a first sample latch (11) for sampling the received data signal (g(t)) with a first clock (f2) and for generating a first sample value (an). The receiver (3) also comprises a second sample latch (13) for sampling a first shifted received data signal (g(t)+V1) with a second clock (f1) and for generating a second sample value (yn). The receiver (3) further comprises a third sample latch (14) for sampling a second shifted received data signal (g(t)−V1) with the second clock (f1) and for generating a third sample value (zn). Finally the receiver (3) comprises a logic unit (15) for recovering data (dn) out of said first, second and third sample values (an, yn, zn).
