摘要： The invention relates to an apparatus and a method for stabilization of the transmission power of a radio during the active transmission phases thereof. Such stabilization is accomplished by measuring the power drop during the active transmission phase. The gain factor of the power amplifier associated with the apparatus is then raised during subsequent time slots, such that the measured power drop is compensated for precisely.

摘要： An oscillator is disclosed that is tunable to discrete values, and includes a tuning element which can be connected via a switching device. A rectifier circuit is connected to the output of the oscillator and forms a clock signal from the oscillator signal. The oscillator circuit contains a phase delay circuit having a switching input, a clock signal input which is coupled to the output of the rectifier circuit, and a switching output coupled to the switching device. The phase delay circuit has a comparison circuit for comparison of a phase of the clock signal that is applied to the signal input with a reference phase. This phase delay circuit is designed to emit a switching signal after application of an activation signal to the switching input and after the phase of the clock signal which is applied to the signal input matches the reference phase. In consequence, the switching process is delayed until the step-function response of the output signal of the oscillator does not cause a sudden phase change in the clock signal.

摘要： A controllable current source circuit and a phase locked loop contained such a circuit are disclosed. The current source circuit such a single switched driver stage for a switched actuation of the loop filter. A continuously switched-on driver stage is introduced into one of several paths of the current source circuit, so that a continuously weaker current is drawn by the loop filter. The currents are preferably stabilized via a current mirror circuit.
