摘要： A system and method for closed loop clock correction includes adjusting two or more input signals comprising at least one in-phase clock and one quadrature clock, and applying adjusted quadrature clock signals to a device capable of generating a 4-quadrant interpolated output clock phase. An interpolated output clock phase is delayed to form a clock for a measurement device. Two or more adjusted input signals are measured on a measurement device over a range of interpolated output clock phases. Errors are determined on the in-phase clock and the quadrature clock using sampled information from the measurement device. The in-phase clock and the quadrature clock are adapted using determined error information.

For instance, a current integrator circuit includes a current integrating amplifier circuit comprising an adjustable circuit element to tune a peaking response of the current integrator circuit, and a peaking control circuit to generate a control signal to adjust a value of the adjustable circuit element as a function of an operating condition of the current integrator circuit. The operating condition may be a specified data rate or a communication channel characteristic or both. The adjustable circuit element may be a degeneration capacitor or a bias current source.

摘要： A data receiver, a method of operating a data receiver, and an integrated coupling system in a data receiver are disclosed. In one embodiment, the data receiver comprises an input terminal for receiving an input data signal, an input amplifier for amplifying selected components of the input data signal, and an input signal path for transmitting specified high-frequency components and a baseline component of the input data signal from the input terminal to the input amplifier. The data receiver further comprises a feed-forward resistive network connected to the input terminal and to the input amplifier. This feed forward resistive network is used to forward a low-frequency drift compensation signal from the input terminal to the input amplifier, using a passive resistive network, to compensate for low frequency variations in the input data signal, and to develop a desired bias voltage at the input amplifier.

摘要： Provision of gigabit-rate data transmission over wireless radio links, using carrier frequencies in the millimeter-wave range (>30 GHz). More specifically, a circuit for detection of amplitude-shift keyed (ASK) or other amplitude modulations (AM) which can be easily incorporated into an integrated circuit receiver system is described, making the receiver capable of supporting both complex IQ modulation schemes and simpler, non-coherent on-off or multiple-level keying signals. Several novel radio architectures are also described which, with the addition of a frequency discriminator network, have the capability of handling frequency shift keyed (FSK) or other frequency modulations (FM), as well as AM and complex IQ modulation schemes. These radio architectures support this wide variety of modulations by efficiently sharing detector hardware components. Disclosed herein are architecture for supporting both quadrature down-conversion and ASK/AM, ASK/AM detector circuit details, AM-FM detector architecture, and an AM-FM/IQ demodulator system and FSK/FM detector circuit details.

摘要： An apparatus and method for an improved hardware implementation of a digital phase shifter which provides a simplified process for phase correction of digital signals and eliminates the use of a lookup ROM and complex digital Multipliers. The digital phase shifter operates by applying a phase correction to complex digital I/Q samples in separate stages, where each stage performs a phase rotation by an amount specified directly by the binary values of an integer input phase. In one aspect, an apparatus for applying a phase shift to a complex digital signal comprises a plurality of phase shift stages each having a phase shift value associated therewith, whereby each of the plurality of phase shift stages selectively applies the corresponding phase shift value to the complex digital signal.
