20140333362 | SLEEP MODE CIRCUIT AND A METHOD FOR PLACING A CIRCUIT INTO SLEEP MODE - A first circuit is configured to communicatively couple to a second circuit including an analog circuit and a digital circuit. The first circuit comprises a lock unit and a sleep unit. The lock unit is configured to receive a lock enable signal and to lock a configuration signal of the digital circuit in response to the lock enable signal. The sleep unit is configured to receive a sleep triggering signal indicating to switch into sleep mode and to generate an off signal to switch off the digital circuit in response to the sleep triggering signal, while the analog circuit remains on. | 11-13-2014 |
20150270842 | Circuit and Method for Adjusting Oscillating Frequency of an Oscillator - A circuit comprises an oscillator, a frequency divider and a comparator. The oscillator generates an oscillating signal (Fvco). The frequency divider is communicatively coupled to the oscillator, divides a frequency of the oscillating signal by a denominator and generates a divided signal. The comparator is communicatively coupled to the oscillator and the frequency divider, and is configured to obtain a first count of the divided signal (Fvco/N) within a predetermined time and a second count of a reference signal within the predetermined time; compare the first count with the second count, and generate a comparison result according to the first count and the second count. The oscillator is further configured to adjust the frequency of the oscillating signal according to the comparison result. | 09-24-2015 |
20160118939 | AMPLIFIER AND AMPLIFICATION METHOD - An amplifier comprises a biasing unit, an amplifying unit and a Schmitt trigger. The biasing unit is configured to generate a bias current which is independent of the power supply, so as to increase power supply rejection ratio. The amplifying unit is connected to the biasing unit and configured to receive an input voltage and generate an amplified voltage based on the biasing current. The Schmitt trigger is connected to the amplifier and configured to generate and output a modified voltage. | 04-28-2016 |
