摘要： A tuning arrangement in a radio receiver includes a front-end circuit having a tunable band-pass filter that is capable of tunably selecting channels within at least one frequency band of an RF signal. A noise source coupled to an input of the tunable band-pass filter introduces a wide-band noise signal into the front-end circuit. A signal detector coupled to an output of the front-end circuit measures at least one signal power associated with a filtered noise signal derived from the wide-band noise signal. A tuning controller, coupled to the tunable band-pass filter by a tuning control signal, adjusts the tuning control signal in response to the at least one measured signal power for tuning the tunable band-pass filter to a desired filter response.

摘要： A method for direct tuning of a radio receiver begins by providing a plurality of frequency-dependent control input signals to an input of the radio receiver. The method continues by, for each of a plurality of frequency-dependent control input signals, determining received signal strength of a current one of the plurality of frequency-dependent control input signals to produce a measured received signal strength, determining whether the measured received signal strength is within a threshold of a known signal strength of the current one of the plurality of frequency-dependent control input signals, when the measured received signal strength is not within the threshold of the known signal strength of the current one of the plurality of frequency-dependent control input signals, incrementally adjusting gain of the radio receiver by a predetermined adjustment value until the measured received signal strength is within the threshold of the known signal strength of the current one of the plurality of frequency-dependent control input signals. The method continues by determining response of the radio receiver based on the incrementally adjusting the gain of the radio when the measured received signal strength is not within the threshold of the known signal strength of the current one of the plurality of frequency-dependent control input signals to produce a determined response. The method continues by comparing the determined response with a desired response of the radio receiver. The method continues by, when the determined response compares unfavorably with the desired response, determining a response offset based on a difference between the determined response and the desired response. The method continues by adjusting response of the radio receiver based on the response offset.

摘要： A television tuner includes an unbalanced tuning circuit and a balanced mixer provided at the next stage of the tuning circuit. An output port of the tuning circuit is grounded through a serial circuit composed of an inductive element and a capacitive means. The output port of the tuning circuit is connected to one input port of the mixer. A connection point provided between the inductive element and the capacitive means is connected to the other input port of the mixer. This permits phases of the signals input to two input ports of the mixer to be inverted to each other.

摘要： An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides programable attenuation and a programable gain low noise amplifier. Frequency conversion circuitry advantageously uses LC filters integrated onto the substrate in conjunction with image reject mixers to provide sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on chip. The filters utilize multi track spiral inductors with shields to increase circuit Q. The filters are tuned using local oscillators to tune a substitute filter, and frequency scaling during filter component values to those of the filter being tuned. In conjunction with filtering, frequency planning provides additional image rejection. The advantageous choice of local oscillator signal generation methods on chip is by PLL out of band local oscillation and by direct synthesis for in band local oscillator. The VCOs in the PLLs are centered using a control circuit to center the tuning capacitance range. A differential crystal oscillator is advantageously used as a frequency reference. Differential signal transmission is advantageously used throughout the receiver. ESD protection is provided by a pad ring and ESD clamping structure that maintains signal integrity. Also provided are shunts at each pin to discharge ESD build up. The shunts utilize a gate boosting structure to provide sufficient small signal RF performance, and minimal parasitic loading.

摘要： An improved satellite receiver front end architecture having a tuner chip and a demodulator/decoder chip. The tuner chip includes a lowpass filter having a configurable cutoff frequency, and the tuner chip uses a frequency signal to provide accurate adjustment of the cutoff frequency. A clock signal having a clock frequency is converted into a control voltage which determines the cutoff frequency of the lowpass filter. Consequently, the cutoff frequency may be increased by increasing the clock frequency, or decreased by decreasing the clock frequency. This configuration provides for improved cutoff frequency control in the presence of signal interference.

摘要： The capacitance value of a variable capacitance element of an RF tuning circuit is controlled in accordance with a control signal Vx. When an automatic search start signal is supplied to a frequency control circuit, frequencies of the local oscillation signal are changed and received frequencies are changed. A storage circuit stores the control data for each predetermined frequency corresponding to the frequency characteristic of the tuning element. When local oscillation frequencies are changed in accordance with an automatic search start signal, an arithmetic circuit computes a control signal Vx in accordance with the data corresponding to the changed received frequency and the control data and thereby, the variable capacitance element is controlled in accordance with the control signal Vx and tuning frequencies are changed so that a tuning frequency coincides with a received frequency. Under the above state, when the electric-field intensity of a received signal reaches a certain level or higher, the frequency control circuit stops the change of frequencies of a local oscillation signal and stops automatic broadcasting-station selection.
