Abstract:

A regulation circuit, incorporated in a single integrated circuit with a first circuit load, which as an input coupled to a power supply which produces a source voltage, and a first output coupled to the first circuit load. The regulation circuit comprises an input capacitor for reducing the magnitude of a voltage change at the first output, and at least a first voltage regulator for producing a predetermined voltage at the first load.

International Classification:

H03B 5/36

US Classification:

331183, 331160

Abstract:

A frequency source having a fast start-up time and low noise in steady state is presented. The frequency source includes an oscillator and a hybrid automatic gain control (AGC) loop that switches between an analog AGC loop at oscillator start up and a digital AGC loop at steady state operation. The analog AGC loop includes a peak detector connected to the oscillator and an error integrator integrating the difference between the peak detector output and a reference voltage. The digital AGC loop includes a comparator comparing the peak detector output and high/low reference voltages, an oscillator counter providing a timer signal, a digital-to-analog converter (DAC) supplied with a digital word, and a low pass filter between the DAC and the oscillator. The timer signal causes a multiplexer to select either the analog AGC loop or the digital AGC loop.

International Classification:

H03F 3/45

US Classification:

330254

Abstract:

An amplifier, tuner, and method of amplification are provided. The amplifier has a pair of transistors. Each transistor has a control terminal and an output terminal disposed between the transistor and a power supply input. A first network is connected between each power supply input and output terminal. The first network contains a first resistor and a first switch connected in parallel with the first resistor. A second network is connected between the transistors. The second network contains a first and second combination. Each of the first and second combinations contains a second resistor and a second switch connected in parallel with the second resistor. The first and second combinations are connected by a third switch.

Abstract:

A variable attenuator and method of attenuating a signal is presented. The variable attenuator contains an input that receives an input signal to be attenuated. A voltage divider between a resistor and parallel MOSFETs provides the attenuated input signal. The MOSFETs have different sizes and have gates that are connected to a control signal through different resistances such that the larger the MOSFET, the larger the resistance. The control signal is dependent on the output of the attenuator. The arrangement extends the linearity of the attenuation over a wide voltage range of the control signal and decreases the intermodulation distortion of the attenuator.

International Classification:

H04B 1/06

US Classification:

4552491, 455254

Abstract:

An amplifier and method of amplifying a signal is presented. The amplifier contains a fixed gain stage, a digitally controllable gain stage, and a continuously variable attenuator connected between the fixed and controllable gain stages. The attenuator and controllable gain stage are controllable such that the gain of the controllable gain stage is decreased when the attenuation of the attenuator reaches a predetermined maximum value and the attenuation of the attenuator is reduced thereafter. The output power level of the amplifier remains constant.
