摘要： A fast blind scan method first initializes pointers to fetch a block of spectrum and then checks whether the block contains a high spectrum signal and whether the difference between a carrier frequency of the high spectrum signal and a start pointer is greater than a first threshold. When the high spectrum signal is absent or the difference is not greater than the first threshold, it checks whether there is a full band channel in the block. When the full band channel exists, a signal detection and parameter extraction operation is performed and the start pointer is set to be a frequency of a second cross point. Then, it checks whether the difference between the start pointer and an end pointer is greater than a second threshold and, if not, a carrier frequency pointer is set to enable a tuner to fetch a next block.

摘要： A temperature sensing device includes a bandgap voltage generator, N mirror current sources, a temperature voltage generator, and a temperature calculating unit. The mirror current sources mirror N mirror currents according to a positive temperature coefficient current. The temperature voltage generator sets the conducting number M of the mirror current sources based on a control signal, so as to generate a temperature voltage. The temperature calculating unit gradually counts the control signal and compares a potential of the temperature voltage with a potential of a reference voltage generated by the bandgap voltage generator after counting the control signal, so as to calculate and obtain temperature information. Thus, the temperature sensing device controls the conducting number M of the mirror current sources to generate the temperature voltage instead of applying serially-connected resistors, so as to reduce a circuit area of the temperature sensing device and reduce noise.

摘要： An analog-to-digital conversion device and a method thereof are provided. The analog-to-digital conversion device includes a first level adjustment unit, an analog-to-digital converter (ADC), and a linear range detection unit. The ADC converts a test signal or a first input signal to generate a test data stream or a first output data stream. In an adjustment mode, the linear range detection unit obtains a conversion curve of the ADC by using the test data stream and determines whether to adjust offset control information according to a linear range of the conversion curve. In an operation mode, the linear range detection unit continues outputting the offset control information. Additionally, before transmitting the first input signal, the first level adjustment unit adjusts a direct-current level of the first input signal according to the offset control information to allow the first input signal to be within the linear range of the conversion curve.

摘要： In a method of automatically selecting audio format for output signal of a tuner, a SAW filter is configured to a bandwidth of 5.5 MHz for filtering IF signal so as to generate CVBS signal and SSIF signal. Then, band-pass filters are used to detect a back porch of the CVBS signal thereby determining whether signal amplitude at a center frequency of 4.43 MHz is greater than that at a center frequency of 3.58 MHz. Finally, a bandwidth of 4.5 MHz is assigned to the SAW filter for filtering the intermediate frequency signal to re-generate the CVBS signal when the amplitude at 4.43 MHz is smaller than that at 3.58 MHz. Further, a video decoder decodes the CVBS signal to determine a video format from NTSC, PAL-M, and PAL-N formats, and an audio decoder decodes the SSIF signal to determine an audio format from MN, BG, DK, and I formats.

摘要： A 4× over-sampling data recovery system consists of a charge pump PLL, a 4× over-sampler, a data regenerator and a digital PLL. The charge pump PLL receives a clock signal and generates a plurality of multiplicative clock signals in response to the clock signal. The 4× over-sampler samples a serial data to generate a M-bit signal according to the plurality of multiplicative clock signals, wherein each bit in the serial data is sampled for four times. The data regenerator sequentially receives and combines two M-bit signals to generate a (M+N)-bit signal. The digital PLL divides the (M+N)-bit signal into (N+1) groups of M-bit data and selects a designated M-bit data from the (N+1) groups of M-bit data to generate a P-bit recovery data.
