Abstract: In a semiconductor integrated circuit, a ground plane conductor 3 is formed in a substrate 9 to oppose to a conducting line 2 formed on the substrate, so as to form a microstrip line. A decoupling capacitor 1 is provided on the substrate 9 and is electrically connected between the conducting line 2 and the ground plane conductor 3 so as to bypass a high frequency current component flowing through the conducting line to the ground plane conductor. Thus, the impedance of the conducting line 2 is stabilized, and a path of a feedback current of a high frequency current component flowing through the conducting line 2 is ensured by the ground plane conductor 3, so that a current loop is minimized, resulting in minimized electromagnetic noises radiated from the current loop.

Abstract: A circuit for reproducing a clock signal from digital signals reproduced from a recording medium makes self-clocking possible. The circuit includes a phase lock loop having a voltage-controlled oscillator that generates an oscillation output at a frequency which is approximately equal to or an integral multiple of the frequency of the clock signal contained in the reproduced signal. A pulse generating device outputs pulses of a fixed amplitude, triggered by the leading or trailing edge of the input signal, to the phase lock loop. An oscillation device outputs pulses having approximately the same period as the clock signal period. The oscillation device is triggered by the leading or trailing edge of the input signal. A selecting device gates the output pulses of the oscillation device to the phase lock loop. The selecting device interpolates the output pulse spacing of the pulse generating device and the output pulses of the oscillation device so that a clock signal output is obtained from the phase lock loop.
