摘要： A radio frequency receiver 30, 32, includes a first component block 12, 16, 18, 20; a second compensating component block 22, 22a-22b, 34; and control circuitry 26 operable for controlling the state (e.g., load, bias, gain) of the first component block. When the control circuitry 26 causes a change in the state of the first component block that is expected to induce a DC offset in a signal, the control circuitry 26 changes the state of the second component block to compensate for an estimate of the DC offset. Preferably, the second component block is a filter 22, 22a-22b, 34, that temporarily changes from a nominal cutoff frequency to an elevated cutoff frequency so that voltage will settle quickly and accurately at an estimated voltage, the estimated voltage being predetermined and based on the state change to the first component block. A method is also described for practicing the invention.

摘要： The present invention provides a method for automatic calibration of a signal path in receivers (e.g., radio frequency receivers) using a noise (and not a specific test signal) as a source and a fast Fourier transform (FFT) of the noise for correcting various parameters related to an inphase/quadrature (I/Q) imbalance in a frequency domain. The present invention (method and apparatus) can provide detecting and correcting an I/Q phase error, an I/Q amplitude error, an absolute corner frequency of the analog baseband filter, and a relative corner frequency of the analog baseband filters just by using the noise as a stimuli. This calibration can be used for a factory calibration or it can be used as an on-site calibration for base stations. Mobile devices can calibrate themselves independently of their location. This reduces the requirements for the test equipment in the manufacturing and maintenance stages.

摘要： In one aspect this invention provides a radio frequency receiver for coupling to an antenna. The receiver includes a downconversion mixer, an amplifier having an input coupled to the antenna and an output coupled to a first input of the mixer for providing a received frequency signal to the mixer and a voltage controlled oscillator having an output coupled to a second input of the mixer for providing a mixing frequency signal to the mixer. In the preferred embodiments the components of the amplifier and the voltage controlled oscillator are arranged to exhibit a substantially identical resonant circuit topology and are implemented in the same integrated circuit. In the preferred embodiments the amplifier and the voltage controlled oscillator each include calibration circuitry coupled to a calibration signal for compensating for integrated circuit component value variations, and where a calibration signal used for the voltage controlled oscillator is used as well for the amplifier.
