  • Analog dynamic memory circuit
    Patent number: 4947371
    Abstract: An analog dynamic memory circuit comprises a time delay element with a variable delay time feedback loop and a time delay element control device which changes the delay time of the time delay element every time when an analog signal circulates in the feedback loop. This analog dynamic memory circuit prevents or avoids superposition of noise signals which have the same phase in the loop circuit, with the result that amplification of noise and tuned waves in the circuit is prevented.
