Filed: 1992-10-22
Abstract: PURPOSE:To provide a large time constant by providing a high-pass filter means provided with the function of feedback for a differential amplifier means between the output means of the differential amplifier means and an output means in the rear stage. CONSTITUTION:A high-pass filter means 4 connected to a differential amplifier means 1 and an output means 5 is provided with the two kinds of amplifier means 31 and 32. Then, one part of an output from the means 4 is fed back to the differential amplifier means 1. On the other hand, the respective resistance values of resistors R6 and R7 at the amplifier means 32 can be suitably changed so that the amplifier means 32 can arbitrarily change the amplification factor. Thus, the resistance value of the high-pass filter means 4 can be apparentially enlarged and as a result, the impedance of the means 4 can be apparentially enlarged.

Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To attain reduction in the current consumption of an external peripheral circuit by providing a selecting means or the like for selecting an address outputted by an address output means and outputting it to an external address bus when a CPU is to access an internal circuit. SOLUTION: When an access area signal SA is H level, a multiplexer 15 selects an address ADD-A outputted by a CPU 10 and outputs it to the external address bus and when the access area signal SA is L level, an address ADD-B outputted from an address setting register 14 is selected and outputted to the external address bus. Thus, when the CPU 10 accesses the internal circuit and is transited into standby mode, the external peripheral circuit is made inactive at the time of access to the internal circuit and the external peripheral circuit can be prevented from turning active at the time of standby mode so that the reduction in the current consumption of external peripheral circuit can be attained.
