摘要：
In a digital-analog hybrid LSI including an analog circuit (2) and a digital circuit (3), the analog circuit (2) includes a circuit for sampling, according to the operation timing of a switch (4), information to be processed by the analog circuit (2) in a capacitor (5). A clock signal generating means (6) generates an operation reference clock signal (b) for the digital circuit (3) so that the change of the clock signal (b) is stopped at a timing when the switch (4) is opened, i.e., during a specified period (T) which includes the high-to-low transition timing of the clock signal. This prevents the analog characteristic of the analog circuit (3) from being degraded by digital noise that is transferred through the junction capacitance of the semiconductor chip (1).
