摘要： A local oscillator generator (LO generator) may be configured to transmit an LO signal to a mixer. The LO generator may include an input buffer configured to generate a first internal oscillator signal based on the input oscillator signal. The LO generator may include a frequency dividing circuit configured to generate a second internal oscillator signal based on dividing a frequency of the first internal oscillator signal. The LO generator may include an output buffer configured to generate the LO signal based on the second internal oscillator signal. The input buffer and the frequency dividing circuit may each be configured to receive a power voltage independently of the output buffer.

摘要： An apparatus includes a chamber main body, a microwave output device that generates a microwave having a bandwidth, a wave guide tube that is connected between the microwave output device and the chamber main body, and tuner that is provided in the wave guide tube. The microwave output device generates a microwave of which power is pulse-modulated to have a high level and a low level. The tuner includes a stub configured to be adjusted a protrusion amount with respect to an internal space of the wave guide tube, a tuner wave detection unit that detects a measured value corresponding to power of a microwave in the wave guide tube at a timing based on the pulse frequency and the setting duty ratio, and a tuner control unit that adjusts a protrusion amount of the stub on the basis of the measured value detected by the tuner wave detection unit.

摘要： A bias-current-control circuit is provided. The bias-current-control circuit includes a transconductance circuit, a constant-current source, and a current-mirror circuit. The transconductance circuit is connected to a node and detects a voltage signal to generate a first current. The constant-current source is connected to the node and generates a tail current. The current-mirror circuit includes a reference current terminal and a bias current terminal, and the reference current terminal is coupled to the node. A second current which flows through the reference current terminal is determined by a current difference between the tail current and the first current. A bias current which flows through the bias current terminal is generated based on the second current. Furthermore, the second current and the bias current are in a predetermined ratio.

摘要： Methods and systems for generating a probability assessment for peak demand reduction for utility customers using a conditional-output energy generator are described. One method includes providing a customer data set and one or more historical generator production data sets for one or more intermittent generators that meteorologically correspond with the customer data set. Time intervals are defined in the data sets and a production distribution curve is generated for each time interval. A simulation is performed using the historical customer consumption data and the production distribution curves to obtain a net demand distribution curve for each time interval. These methods and systems may provide probability-based economic evaluation of consumption management systems.

摘要： Various techniques for automatic amplitude control of an oscillator are described. An apparatus includes an oscillator circuit configured to generate an oscillating signal. The apparatus includes a feedback circuit configured to control a bias signal of the oscillator circuit to maintain a target peak amplitude of the oscillating signal based on a current-mode indicator of a peak amplitude of the oscillating signal and a reference current. The feedback loop includes a rectifier circuit configured to generate the current-mode indicator and a summing node configured to provide a bias control signal based on a difference between the current-mode indicator and the reference current. The feedback circuit may include a capacitor coupled to the summing node and configured to accumulate charge according to the difference. A magnitude of the current-mode indicator may be at least two orders of magnitude less than a magnitude of the current through an output node of the oscillator circuit.

摘要： An oscillator includes: inverters that are connected in a loop shape and of which the number is an odd number greater than or equal to three; and a delay section that delays change in a voltage which is input to one inverter of the odd number of inverters. The one inverter is a schmitt trigger inverter. The schmitt trigger inverter includes a current source, and a resistor in which current supplied by the current source flows. A hysteresis width of the schmitt trigger inverter depends on the current which flows in the resistor.
