  • Analog signal generator and digital circuit driver, and imaging apparatus
    Patent number: 7352315
    Abstract: An analog signal generator and digital circuit driver comprises an analog signal generator driving block and a digital circuit driving block. The analog signal generator and digital circuit driver is connected to an analog signal generator and to a digital circuit separately. The analog signal generator generates an analog signal. Noise is generated at the digital circuit during a first operation. The analog signal generator driving block outputs a first driving signal to the analog signal generator. The first driving signal causes the analog signal generator to generate the analog signal. The digital circuit driving block causes the digital circuit to carry out the first operation between two first driving signals, consecutively output from the analog signal generator driving block at different timings.
