摘要： Circuits and methods are given, to realize and implement an oscillator circuit with an Average Controlled (AC) Resonator Driver. A newly introduced additional Field Effect Transistor within a voltage average stabilizing regulation loop controlling the crystal oscillator's amplifier element produces an average voltage value stabilized sinusoidal oscillation signal which is then transformed into a square wave with a precise duty-cycle of exactly 50%. Said circuits and methods are designed in order to be implemented with a very economic number of components, capable to be realized with modern integrated circuit technologies.

摘要： Circuits and related methods to detect efficiently a short-circuit condition of a pad of an IC device efficiently using a comparator and a current mirror configuration have been achieved. The IC device to be tested is free floating. The current mirror configuration comprises four branches, a biasing branch, a first comparator branch, a second comparator branch and a measurement branch. The measurement branch is connected to a pad of the IC device and a measurement current is charged on to the pad. Said measurement current is mirrored from the current of the biasing branch and the measurement current is mirrored to the second comparator branch. Furthermore the current of the biasing branch is mirrored to the first comparator branch using a scale that the current of the first comparator branch is smaller than the current of the biasing branch. In case of a short-circuit the current of the measurement branch can flow and correspondently the current of the second comparator branch is larger than the current of the first comparator branch and hence the comparator, comparing both currents, can indicate a short-circuit situation.

摘要： A method and circuits to limit the output load current of a current driven LDO voltage regulator are disclosed. The current through a second pass transistor, being in parallel to a first pass transistor and being a fraction of the current through the first pass transistor is measured and compared with a reference current. In case the current through the second pass transistor is larger than this reference current the current through the gates of both pass devices is reduced and thus the output load current of the voltage regulator is limited.

摘要： Systems and methods to achieve a logarithmic digital-to-analog converter (DAC), which is easy to be implemented, and requiring reduced chip space have been disclosed. The logarithmic DAC is created by a simple and easy to scale linear DAC, which is linearly scaling a predefined voltage range. The output voltage of the linear DAC is converted to a logarithmic current value directly by the voltage-current characteristic of an integrated diode.

摘要： A circuit and a related method to measure very precisely the resistance Rm of a small resistor independent from process and temperature variations. This resistor may be the RON resistance of an external sensor or e.g. the resistance of a safety device as a squib. A constant current source provides a current IBIAS causing a voltage drop Vm at the resistor to be measured. Using a configuration of operational amplifiers and current mirrors, wherein one of the current mirrors has a gain of n, an output voltage VOUT is achieved, which is defined by VOUT=n×Rm×IBIAS. The gain n of a current mirror allows a very precise measurement of the resistance Rm of the resistor to be measured. The output voltage is finally converted from analog to digital values.

摘要： A low dropout voltage regulator comprising a first output voltage regulation loop with a NMOS transistor as a pass element and a second output voltage regulation loop with a PMOS transistor as a pass element. The NMOS transistor is used for small current loads up to 1 mA, the PMOS transistor is used for higher current loads from 1 mA and up. A current sense buffer senses the current through the NMOS transistor and controls the gate of the PMOS transistor accordingly. Good load transient operation is achieved without the need of an external load capacitor.
