摘要： An apparatus and method for driving an output signal in a high speed integrated circuit. The apparatus and methods enable the output voltage swing from the driver to exceed the breakdown voltage of any individual element in the output driver. A high speed driver can utilize one or more transistors in a stacked configuration, such that the breakdown voltage of the entire stacked configuration is based on the number of transistors in the stack. The driver is configured to distribute the output voltage substantially equally among each of the stacked transistors, such that the driver is able to source an output voltage swing that is greater than the breakdown voltage of any individual transistor in the driver.

摘要： A scalable and ultrasensitive frequency-shift magnetic array scheme. The theoretical limit of the sensor noise floor is shown to be dominated by the phase noise of the sensing oscillators. To increase the sensitivity, a noise suppression technique, Correlated Double Counting (CDC), is described with no power overhead. As an implementation example, a 64-cell sensor array is designed in a standard 65 nm CMOS process. The CDC scheme achieves an additional 6 dB noise suppression. The magnetic sensing capability of the presented sensor is verified by detecting micron size magnetic particles with an SNR of 14.6 dB for a single bead and an effective dynamic range of at least 74.5 dB. Applications in biosensing are contemplated, among other possible uses. Measurement of electrical properties is also contemplated.

摘要： According to one aspect, an integrated magnetic particle measurement device for detecting a presence or absence of magnetic particles in a sample volume includes at least one sensor cell having a differential sensor pair. An active sensor oscillator frequency is responsive to one or more magnetic particles situated within a sample volume. The sensor cell is configured to be operative in the absence of an externally applied magnetic field. A frequency measurement circuit provides as a time-multiplexed output a first count representative of the active sensor oscillator frequency and a second count representative of the reference sensor oscillator frequency. A calculated difference between the first count and the second count is indicative of a presence or an absence of one or more magnetic particles within the sample volume. An integrated magnetic particle measurement system array and a method for detecting one or more magnetic particles are also described.

摘要： Third-order intermodulation products (IM3) are attenuated in RF receivers by providing a typical main signal path and a parallel auxiliary signal path in which the IM3 products are accentuated, and the output from the main signal path is adaptively filtered to attenuate the IM3 products. In one embodiment, a multirate filter bank (MRFB) with asymmetric analysis and synthesis sections is used to detect and isolate the IM3 products. In another embodiment an analog nonlinear term generator is placed at the front of the auxiliary signal path. The analog nonlinear term generator takes advantage of the nonlinearities of a differential MOSFET circuit and a multiplier to extract the IM3 products in the RF input signal. The outputs of the main signal path and the auxiliary signal path are inputs to a complex least mean squares filter to attenuate the IM3 products in the resulting signal.
