摘要： In a method for avoiding transients during switching processes in integrated circuits, a module of the integrated circuit is switched from a first operating state to a second operating state, a load change occurring thereby. In this case, it is ensured that the occurring quotient of load change and time duration for the transition from the first operating state to the second operating state does not exceed a predetermined limit value, thereby reducing or avoiding transients associated with such switching.

摘要： The method is based on a signal interval (DB) which comprises a first part (ET) (which is modulated using a first modulation method (GFSK)) of the signal interval and a second part (which is modulated using a second modulation method (DMPSK)) of the signal interval. The channel parameters (c(i)) relating to the second part (which is modulated using the second modulation method) of the signal interval are determined using a received data signal (a(i); p(i)) from the first part (ET) of the signal interval (DB).

摘要： A radio receiver with a low intermediate frequency has a first mixer stage that can be fed with a modulated input signal and at whose output a complex intermediate frequency signal can be derived. Connected downstream of the first mixer stage is a limiting amplifier at whose output the intermediate frequency signal is present in a discrete-value and continuous-time fashion. A sampling device, for sampling the intermediate frequency signal, and a digital demodulator unit are connected to the output of this limiter. The demodulated input signal can be derived at the output of this digital demodulator unit. The present radio receiver requires a low chip area in conjunction with low power consumption, but offers a high sensitivity and accuracy based on the digitally implemented demodulation.

摘要： The invention specifies a circuit arrangement with a phase locked loop (1), which can be used as a mobile radio transmitter, in particular. The reference frequency for the PLL (1), which is provided by means of the source (3), is multiplied by a multiplier (10) and is down-converted to an intermediate-frequency level in a down-conversion mixer (9) using the output signal from the PLL, and is evaluated such that a modulator (13) connected to the input of the oscillator (6) can be trimmed. The inventive principle is used to advantage in two-point modulators and allows inexpensive, integratable mobile radio transmitters with good noise characteristics.

摘要： An electronic device is equipped with an oscillator interface to be coupled to an oscillator crystal of an oscillator element. The electronic device includes an oscillator circuit which is coupled to the oscillator interface and generates an oscillator signal. The electronic device is further provided with a temperature measurement interface to be coupled to a temperature sensor of the oscillator element so as to receive the temperature signal. For accomplishing temperature compensation, the electronic device is provided with a measurement controller coupled to the measurement interface and configured to measure a first value of the temperature signal at a first point of time and a second value of the temperature signal at a second point of time. A frequency drift estimator is provided so as to estimate a frequency drift of the oscillator signal on the basis of the first value of the temperature signal and a second value of the temperature signal. By means of a compensation logic, a frequency compensation signal for the oscillator circuit is generated on the basis of the estimated frequency drift.
