8577305 Circuits and methods for generating oscillating signals November 5, 2013
Embodiments of the present invention may be used to generate oscillating signals. One embodiment of the present invention includes a circuit that receives a differential signal to be divided. The circuit converts the differential signal into an injection signal. The injection signal is
8284824 On-Chip IQ imbalance and LO leakage calibration for transceivers October 9, 2012
The disclosure can provide methods and systems for autocalibrating a transceiver. The method can include upconverting a bandpass input signal by mixing the bandpass input signal with a first local oscillator signal to form an initial transmitter signal. The initial transmitter signal can
8139670 Modular MIMO transceiver architecture March 20, 2012
A scalable N.times.N single-chip dual-band MIMO RF transceiver module compatible with the IEEE 802.11n standard for WLAN applications is provided. A modular design approach allows a transceiver of substantially any dimension to be created on a single chip that may be easily integrate
7890132 Systems and methods for calibrating power regulated communication circuitry February 15, 2011
Systems and methods are provided for calibrating the control mechanism in a communication circuit to allow the communication circuit to maintain a desired output power level. The communication circuit includes a variable gain adjustment circuit and a power amplifier, which operate togeth
7856048 On-chip IQ imbalance and LO leakage calibration for transceivers December 21, 2010
The disclosure can provide methods and systems for autocalibrating a transceiver. The method can include upconverting a bandpass input signal by mixing the bandpass input signal with a first local oscillator signal to form an initial transmitter signal. The initial transmitter signal can
7808322 System and method for modifying output power of an information communication system October 5, 2010
A system comprises a variable gain amplifier (VGA) that amplifies an input signal with a gain that is based on a gain control signal. A power amplifier receives an output of the VGA. Memory switches between at least two of N output power settings each including a predetermined reference
7761067 Iterative filter circuit calibration July 20, 2010
Apparatus, systems, and methods implementing techniques for calibrating a filter circuit. A comparator generates an output based on a filter output amplitude signal and a reference amplitude signal. A calibration logic unit receives the comparator output and produces a component code tha
7738904 Systems and methods for calibrating power regulated communication circuitry June 15, 2010
Systems and methods are provided for calibrating the control mechanism in a communication circuit to allow the communication circuit to maintain a desired output power level. The communication circuit includes a variable gain adjustment circuit and a power amplifier, which operate togeth
7610022 Filter circuit with negative transconductance October 27, 2009
Apparatus, systems, and methods implementing techniques for filtering signals are described. A filter circuit receives an input signal and produces a corresponding filtered signal. The filter circuit has a transfer function that relates the filtered signal to the input signal. The tr
7173489 Programmable gain voltage buffer February 6, 2007
A programmable gain voltage buffer circuit with a programmable gain may include transistors in parallel with resistors. The transistors may be used as variable resistors, with the resistors predominating the equivalent resistances at output points in different branches of the buffer
7167045 System and method for modifying output power of an information communication system January 23, 2007
A system for communicating information includes a variable gain amplifier (VGA) responsive to an input signal and a gain control signal for controlling a gain of the VGA. The system also includes a power amplifier responsive to the VGA. An output power level of the power amplifier is
