摘要： A voltage-controlled oscillator includes a resonator circuit and a voltage source. The resonator circuit includes a capacitive circuit that has a plurality of analog voltage controlled capacitive elements coupled to one another. The voltage source is coupled to the resonator circuit and provides a voltage to the plurality of analog voltage controlled capacitive elements. Each of the plurality of analog voltage controlled capacitive elements is activated as a function of the voltage thereby increasing linearity of a frequency tuning voltage parameter of the resonator.

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 invention relates to a device and a method for converting a digital signal having a plurality of data-bits into a filtered analog signal. A device according to the invention includes a delay element arranged to produce one or more differently delayed version of the digital signal and a digital-to-analog conversion circuitry arranged to convert the digital signal and the one or more differently delayed, and possibly differently scaled, versions of the digital signal into analog signals and to produce the filtered analog signal as a combination of the analog signals. Therefore, the device constitutes not only a digital-to-analog-converter but also a finite impulse response filter.

摘要： An apparatus (100) and corresponding method for use by a first transceiver in saving power when communicating over a wireless communication system with a second transceiver, the first having an operating cycle including an interval in which it sends transmit power requests to the second, the transmit power requests being made based on measurements of the signal received by the first and performed in an interval of the operating cycle in which the operational parameters correspond to a power control measurement state. The method includes: when no power control measurements are being made, a step (44b) of enabling receiver tuning to adjust the receiver operational parameters to place the receiver in a less power-consuming internal state.

摘要： This invention describes a method for a component/system level design of an adaptive radio receiver in electronic communication devices (e.g., mobile phones) by providing an automatic digital tuning of a voltage controlled oscillator of a phase locked loop (PLL) instead of a prior-art pre-calibration. A normal PLL for frequency locking is used which does not need any additional pre-calibration blocks to account for different temperatures or any other extreme conditions. If the current switch setting does not allow the locking, i.e., the VCO output signal frequency is still far away from a reference frequency, the PLL “coarse” tuning will cause the switch condition to change and bring the frequency within a reasonable range using an additional phase detector PD2 loop.

摘要： An RF VCO (260A) forms, in the preferred embodiment, a part of a dual mode mobile station (100). Also disclosed is a method for operating the VCO. The VCO is operated in a first frequency band using a first inductance (300A) that forms part of a first resonant circuit (parallel resonance), and the VCO is switched for operation to a second frequency band by the closing a switch (M5) that causes a second resonant circuit (serial resonance) to be inductively coupled to the first resonant circuit. The second resonant circuit includes a second inductance (300B), and preferably includes at least one frequency tunable component, such as a varactor (VR3, VR4), for adjusting the resonant frequency of the second resonant circuit. The second inductance is center tapped, and the switch, such as a MOS transistor, is coupled in series between two ends of the center tapped inductance. The first frequency band may include 3.6 GHz (a double frequency GSM band) and the second frequency band may include 4.3 GHz (a double frequency WCDMA band). Additional operational bands can be also be used. In the preferred embodiment the first inductance forms part of a transformer primary fabricated in an integrated circuit, and the second inductance forms part of the transformer secondary that is fabricated in the integrated circuit so as to underlie the first inductance. A signal detector (D1, D2) may be provided that is responsive to a signal induced in the transformer secondary, and the signal detector has an output coupled to a closed loop control circuit (310) for controlling a magnitude of a signal output from the VCO. A further input to the closed loop control circuit may be a signal that is indicative of communication channel conditions, and the current consumption of the VCO circuit is maintained at a level that is adequate to ensure operation with the communication channel conditions. A passive buffering circuit (320) is provided for coupling an output of the VCO circuit to a further circuit, such as a mixer, thereby reducing the total VCO current considerably.
