Latest Patents

Jiunn-Fu Liou holds a patent for a "High-frequency clock generator using lower frequency voltage controlled." This invention features a low noise high-frequency clock generator that utilizes a low-speed voltage-controlled oscillator. The design incorporates 2m differential delay elements arranged in series in an inverting configuration, where m is an integer greater than 0. The output of the 2mth delay element is connected to the input of the first delay element in a non-inverting configuration. The clock generator also includes M 2-input exclusive NOR gates, with respective input pairs taken from the positive terminal inputs of adjacent delay elements. Additionally, an m-input OR gate is coupled to the m-outputs from the exclusive NOR gates to generate the clock output signal. The variable delay associated with each delay element is controlled by a control delay signal, allowing for frequency adjustments based on the time delay.
