    摘要： An aliasing sampler probe for detecting plasma RF voltage and current employs a sampling signal with a sampling rate slower that the RF fundamental frequency selected to produce an aliasing waveform at an aliasing frequency that is several orders of magnitude below the RF fundamental frequency. In one embodiment, the RF power is applied at 13.56 MHz. and sampling pulses have a sampling rate of 2.732 MHz to produce replicas of the RF voltage and current waveforms at an aliasing frequency of about 100 KHz. The aliasing replicas preserve phase and harmonic information with an accuracy that is not available from other sampling techniques.

    摘要： Modern electronic devices are becoming smaller while the need to critically locate acoustic sensors or transducers, e.g., microphones, is increasing in order to provide improved intelligibility in adverse environments. The acoustic transducers can be used in arrays with their outputs processed in beam forming and noise cancellation algorithms. The use and creation of features on the surface of a small package to deal with the problem of achieving high performance solutions in a limited space are disclosed herein. For example, embodiments of electronic communication devices (10) include acoustic transducers (26) integrated with other features such as a volume control (34, 50), an antenna (87, 260, 280), an adapter (300) which can be coupled to an input/output jack (90) and an accessory connector, or a projection (98).

    摘要： An RF generator has an analog feedback circuit in combination with a digital levelling assist circuit to compensate for non-linearities in the power metering circuit that measures the RF output energy. The digital leveling assist circuit has a digitizer with inputs coupled to receive the measured power voltage supplied from the power metering circuit and a power demand voltage. The digitizer has outputs that provide digital representations of the measured power voltage and the power demand voltage to a digital control element that derives a digital correction factor based on these digital representations. A d/a converter coupled to the digital control element provides a correction voltage corresponding to this digital correction factor, and this is furnished to a summing circuit that combines the correction voltage with the power demand voltage and with a control voltage that is supplied by the analog feedback circuit. The leveling assist circuit increases the accuracy of control of the RF output power with respect to the power demand voltage, without sacrificing the speed of the analog feedback circuit.

    摘要： The present control circuit and method extends the operating range of digitally sampled control loops. A programmable output of a generator is controlled. The programmable output includes a an output level having a corresponding set point. The generator has a drive input that is driven to an actual drive point for controlling the output level of the programmable output. A set point corresponding to a requested output level is determined. A predicted drive point is then determined. The actual drive point of the generator drive input is forced to the predicted drive point. The output level of the programmable output is sensed. A digital output signal that is representative of the sensed output level is generated. The actual drive point of the generator drive input is controlled based on the digital output signal, such that the output level of the programmable output is controlled. The actual drive point corresponding to the requested output level is then stored.

    摘要： A high-power radio-frequency amplifier acts on periodic pulses of RF energy. The bias is controlled for each of a bank of FETs or other amplifier devices that constitutes the main power stage. A sample of bias current is obtained during a blanking period on the front porch of the RF gating period. Quiescent drain current is measured, and stored on a sample/hold circuit. A digital signal processor provides bias values that are sent via a D/A converter to biasing circuits that add the bias levels to the input RF signal. If the bias current is above or below a desired level, the stored bias level is decreased or incremented respectively. A timing control circuit gates the sample/hold circuit and switches in advance of the biasing circuits. The timing control circuit also creates a blanking signal to apply to an attenuator to produce a null region during the first 100 microseconds of the gating signal. A thermal sensor is coupled to one or more amplifying devices for presetting the operating voltage when operation has been interrupted for a predetermined period of time.
