  • Patent number: 11099600
    Abstract: To improve a timing error detection accuracy in a semiconductor integrated circuit provided with storage devices operating in synchronization with a clock signal. A delay part delays a data signal by two mutually-different delay times and outputs it as first and second delay signals. A holding part holds the first and second delay signals in synchronization with a timing signal for giving an instruction on a predetermined capture timing. A setup time detection part detects whether or not one of the first and second delay signals held within a setup-time detection period from a predetermined start timing to the predetermined capture timing has changed. A hold time detection part detects whether or not the other of the first and second delay signals held within a hold-time detection period from the predetermined capture timing to a predetermined end timing has changed.

  • Patent number: 5929706
    Abstract: An automatic gain control method and device capable of maintaining the gain within a predetermined proper range by first amplifying an input analog signal from a microphone or the like, then sampling the amplified analog signal while comparing the voltage thereof with a predetermined reference voltage, and when the number of times that the voltage of the amplified analog signal is higher than the reference voltage exceeds a predetermined number of times, varying the gain of the amplified analog signal stepwise in response to every excess beyond the predetermined number of times. Consequently it becomes possible to eliminate the necessity of an input amplifier of a sufficient bandwidth and an A-D converter, hence realizing manufacture of an improved device composed of a single-chip CMOS integrated circuit, with further advantages of minimizing the number of required component parts, reducing the production processes, achieving a higher integration density and lowering the power consumption.

  • Patent number: 5631648
    Abstract: A signal-processing circuit adapted for signal compression and expansion performed in the transmitter and receiver of mobile communication equipment. The signal-processing circuit comprises a multiplication type D/A converter to which an analog signal is applied, a level detector circuit that detects the level of the analog signal, and an A/D converter. The D/A converter converts the analog input signal into an analog output signal having an amplitude corresponding to digital control data. The A/D converter digitizes the output signal from the level detector circuit and supplies it as said digital control data to the D/A converter. These circuits can be fabricated from CMOS circuits.
