Latest Patents

Ju-Ming Chou holds a patent for a clock generator designed to reduce the effects of phase shift errors caused by mismatches in delay units. The invention proposes the addition of a set of averaging amplifiers and averaging impedances, such as resistors, into the clock generator circuit. This design allows for improved performance by connecting the outputs of all delay units to the inputs of the averaging amplifiers. The averaging impedances link the outputs of adjacent amplifiers, forming a closed loop that mitigates phase shift errors. The output impedance of the averaging amplifiers approaches infinity, ensuring that most signal currents pass through the averaging impedances, thus achieving optimal averaging effects. Additionally, the invention employs a voltage-mode phase interpolation technique for enhanced phase resolution and increased output phases. The folding architecture utilized in this clock generator enables the output of high-frequency clock signals at low-frequency operating clocks.
