摘要： An apparatus for controlling slew rate is coupled to two adjustable voltage rails. The output of the apparatus is coupled to the gate of a switching element. By employing two adjustable voltage rails, the slew rate of the switching element is proportional to the voltage difference between the first adjustable rail and the second adjustable rail. The slew rate control apparatus can be applied to a variety of switching elements including N channel Field Effect Transistors (NFETs), P channel Field Effect Transistors (PFETs), current mode logic circuits and level shifter circuits.

摘要： A high accuracy on-chip thermal sensor includes an integrated circuit and sensing elements. The thermal sensor finds application in various mobile and battery powered devices and includes a processor that analyzes a measured temperature signal and decides if the thermal sensor operates in low or high power operational mode, or if the device's CPU is to be reset. A method utilizing the thermal sensor includes making comparisons to two threshold temperatures and operating at low power mode below the first threshold temperature, high power mode between the two threshold temperatures and causing reset if the second threshold temperature is exceeded. Low power operational mode includes a lower clock frequency, lower bias current and lower power consumption. Higher power operational mode is used when the upper threshold temperature is being approached and includes a higher data sampling frequency and more accurate temperature control and uses higher power.

摘要： A method of controlling a regulator includes turning on a first driver during a first cycle for a first time period. A second driver is turned on during the first cycle for a second time period. The first and second drivers are off during the first cycle for a third time period. The first time period is adjusted to become an adjusted first time period for a second cycle based on a ratio and a voltage difference between a peak value of the output voltage and a first voltage during the first cycle. The ratio refers to the first time period over the first time period and the second time period.

摘要： A noise shaper that compares an input signal to a feedback output signal, which is a truncated version of the input signal, and generates the difference between the two signals (i.e., the error). The noise shaper then integrates the errors by adding to the error multiple of its delayed versions, and quantizes the integrated errors in such a way that the spectrum of the quantization noise is shaped toward high frequencies to be removed by a LC low-pass filter used in conjunction with the noise shaper. The low frequency content of the desired signal is mostly unaffected.

摘要： A level shifter receives an input voltage signal and produces an output voltage signal. The level shifter includes a first inverter, configured to operate at a potential difference between a first voltage V1 and a second voltage V2. The output from the invert is capacitively coupled to an input of a latch circuit via a capacitor. The capacitor has a first terminal connected to the output terminal of the first inverter, and further has a second terminal. The level shifter has a resistor connected to a third voltage V3 and to the capacitor for tying the input to the latch circuit to a desired voltage. The latch circuit is configured to operate at a potential difference between a fourth voltage V4 and a fifth voltage V5. The latch has an input node connected to the resistor and the capacitor, and further has an output node connected to an output node of the level shifter.

摘要： A digital controlled battery charger comprises a power converter, a voltage sensor, a current senor, a mode selector and a digital controller. The voltage sensor and current sensor detect the voltage of a rechargeable battery and the current flowing through the rechargeable battery respectively. The mode selector selects a feedback signal from either the output of the voltage sensor or the output of the current sensor. The digital controller receives the selected feedback signal and generates a pulse width modulated signal for the power converter. Additionally, the digital controller is capable of dynamically adjusting its coefficients so that the control loop can maintain a stable system when the battery charger operates in different battery charging phases.
