Abstract
A power voltage of a power source circuit is produced by amplifying a threshold voltage difference of an operational amplifier by an amplification factor corresponding to a dividing ratio of a resistance dividing circuit. The power source circuit is integrated on a CMOS substrate together with a computer block. A plurality of analog switches are associated with the resistance dividing circuit to stabilize the power voltage of the power source circuit. One of these switches is selectively closed to change the dividing ratio of the resistance dividing circuit in accordance with actuation data stored in a control register.
