    • The invention relates to an integrated measurement system to detect a quantity of magnetic particles in a sample. The measurement system includes a substrate. An electromagnetic (EM) structure disposed on the surface of the substrate is configured to receive a sample including the magnetic particles in proximity thereof. The integrated measurement system also includes an electrical current generator disposed on the surface of the substrate which is electro-magnetically coupled to the EM structure. The electrical current generator is configured to cause an electrical current to flow in the EM structure. The integrated measurement system also includes an effective inductance sensor disposed on the surface of the substrate which is configured to measure a selected one of an effective inductance and a change in effective inductance. The invention also relates to a method to determine the number of and/or the locations of the magnetic particles in a sample.

    • A feedforward error-compensated receiver for minimizing undesired odd-order nonlinear distortion products. The receiver includes a first receiver path configured to receive an input signal. The first receiver path outputs a signal including at least one baseband (BB) frequency. At least one second receiver path is configured to receive the input signal and to provide a second receiver path output signal. The second receiver path includes at least one odd-order nonlinear distortion reference generator. The at least one odd-order nonlinear distortion reference generator and the mixer are configured to generate a synthetic odd-order nonlinear distortion signal. A combining element is configured to receive the output signal from the first path and the output signal from the second receiver path output and to combine the signals such that the odd-order nonlinear distortion signals are substantially attenuated at an output of the combining element.

    • An equalizer for serial data communications can be configured to compensate for the effects of deterministic jitter. The equalizer can be configured to compensate a received serial data stream for the effects of data-dependent jitter as well as duty cycle distortion jitter. The equalizer can be configured to determine the value of one or more previously received symbols and compare them to a recovered symbol. The equalizer can adjust a variable delay positioned in the serial data path to introduce a delay into the data path that is based in part on the received data stream. The equalizer can be configured to vary the delay when any of the one or more previously received symbols is different from the recovered symbol, and can be configured to maintain a constant delay if the one or more previously received symbols is the same as the recovered symbol.
    • 串行数据通信的均衡器可以配置为补偿确定性抖动的影响。 均衡器可以配置为补偿接收的串行数据流,以获得与数据相关的抖动以及占空比失真抖动的影响。 均衡器可以被配置为确定一个或多个先前接收的符号的值,并将其与恢复的符号进行比较。 均衡器可以调整位于串行数据路径中的可变延迟,以将延迟引入到部分基于所接收的数据流的数据路径中。 均衡器可以被配置为当一个或多个先前接收到的符号中的任一个与恢复的符号不同时,改变延迟,并且如果一个或多个先前接收到的符号与恢复的符号相同,则可以配置为保持恒定的延迟 。
