  • Patent number: 9698852
    Abstract: A wireless data transceiver comprises a local oscillator configured to generate a first time-varying signal of a first frequency at an output of the local oscillator. The transceiver further comprises a local oscillator interface circuit coupled to the local oscillator. The local oscillator interface circuit is configured to generate a second time-varying signal of the first frequency with negative conductance at an output of the local oscillator interface circuit. The negative conductance is generated based on capacitive degeneration. The transceiver further comprises a frequency mixer coupled to the output of the local oscillator interface circuit. The frequency mixer is configured to generate a third time-varying signal of a second frequency based on the second time-varying signal.

  • Patent number: 9509351
    Abstract: A method includes providing a highly linear front end in a Radio Frequency (RF) receiver, implementing a high Effective Number of Bits (ENOB) Analog to Digital Converter (ADC) circuit in the RF receiver, and sampling, through the high ENOB ADC circuit, at a frequency having harmonics that do not coincide with a desired signal component of an input signal of the RF receiver to eliminate spurs within a data bandwidth of the RF receiver. The input signal includes the desired signal component and an interference signal component. The interference signal component has a higher power level than the desired signal component. The method also includes simultaneously accommodating the desired signal component and the interference signal component in the RF receiver based on an increased dynamic range of the RF receiver and the high ENOB ADC circuit provided through the highly linear front end and the high ENOB ADC circuit.

  • Publication number: 20140162573
    Abstract: A wireless data transceiver comprises a LO, a frequency divider, a tuning voltage buffer, and a controller. The LO generates a LO signal based on a buffer signal. The frequency divider is coupled to the LO and generates a frequency divider signal based at least partly on the LO signal. The tuning voltage buffer is in electrical communication with the frequency divider and the LO and generates the buffer signal based at least partly on the frequency divider signal. The controller adjusts a voltage of the buffer signal based on a selected channel of the wireless data transceiver.

  • Patent number: 8473535
    Abstract: A first system and method relates to an analog current-mode method using branch systems. In the analog current-mode implementation, multiple branches systems can be scaled according to filter coefficients and switched using known data points. Positive coefficients can add current to the summing node, while negative coefficients can remove current from the summing node. Switches can be implemented with quick charge/discharge paths in order to operate at very high data rates. A second system and method relates to a digital look-up table based high-speed implementation. In the digital implementation, outputs can be pre-calculated as an n-bit output word that drives an n-bit DAC. Each bit of the n-bit word can then described as an independent function of the known data points. Each such function can be implemented as a high-speed combinational logic block. Both systems and methods enable the implementation of pulse shaping filters for multi-gigabit per second data transmission.

  • Patent number: 8378874
    Abstract: An analog to digital converter for operating at high speeds can be implemented with a micro-comparator/sampler, an encoder, and a selector. The micro-comparator includes an input from an antenna of a receiver/transceiver system; a transistor pair; reset transistor; cascaded inverters; an inverter circuit; a buffer; and a D flip flop circuit. Depending on the number of micro-comparator/samplers placed in parallel, a number of bits can be generated. For example, 15 bits from 15 different micro-comparator/samplers can be inserted into a 15 to 4 bit encoder to generate 4 bits.

    Abstract: A flange extender for use with an injection device is described. The flange extender includes first and second flange extender pieces and a locking mechanism to lock the first and second flange extender pieces to one another. In one embodiment, the locking mechanism includes each piece having a locking finger extending from the piece and an aperture adapted to receive the locking finger. The first and second flange extender pieces extend in a direction transverse to a main axis of the injection device to thereby provide a surface area for manual manipulation of the injection device during an injection. The first and second flange extender pieces also attach to each other on opposite sides of the injection device.
