Provided is a clock signal generation circuit. The clock signal generation circuit includes a control word generation circuit, an initial clock generation circuit and a spread spectrum clock generation circuit, wherein the control word generation circuit is connected to the initial clock generation circuit and the spread spectrum clock generation circuit; the initial clock generation circuit is further connected to the spread spectrum clock generation circuit.

Clock signal generation circuit and method, and electronic device

A lever shifter includes an output driver and a high-side gate driver. The high-side gate driver is configured to drive the high-side output transistor, and is coupled to an on pulse signal line that conducts an on pulse, and is coupled to an off pulse signal line that conducts an off pulse. The high-side gate driver includes a blocking circuit configured to enable generation of a drive signal to the high-side output transistor based on a voltage of a first of the on or off pulse signal line being greater than a first predetermined amount and a voltage of a second of the on or off signal line being less than a second predetermined amount.

High voltage level shifter with short propagation delay

A data reception circuit removes reliance on stacked transistors providing analog logic processing. A first trigger element outputs an up signal in response to receiving an indication of receipt of a data signal by a receiving device without consideration of an output signal from the receiving device. A second trigger element outputs a down signal in response to receiving an indication of receipt of a data signal by a receiving device without consideration of an output signal from the receiving device. Switches control provision of signals to a received signal line for the receiving device in response to the outputs of the trigger elements. A blocking feedback circuit provides a blocking signal for the receiving device to effect blocking the receiving device from sending data to the sending device when the receiving device is receiving data from the sending device.

High speed data transmission

The present invention provides a method and a system for improving the precision of element measurement based on laser-induced breakdown spectroscopy. The method comprises: press-forming a sample to be measured with a tablet press; making a cavity on or immediately above a surface of the press formed sample; forming a layer of aerosol immediately above the surface of the sample to be measured with the components thereof completely identical to those of the sample to be measured; testing the sample to be measured by using a laser-induced breakdown spectroscopic system, so as to obtain the intensities of the characteristic spectral lines of a target element in the sample to be measured; and determining the concentration of the target element in the sample to be measured according to a calibration curve of the target element in prearranged calibration samples.
