Abstract

PURPOSE:To secure a monolithic constitution in a miniature size and high density onto the semiconductor substrate even through the device may feature a large integration constant by connecting the 1st capacitor to the input terminal of the integrating circuit. CONSTITUTION:Capacitor 2 for integration is inserted between the input and output ends of reverse amplifier A. While capacitors C11, C12 and C13 are connected via the switch. In other words, the serial circuit of capacitor 12 and the parallel circuit of capacitors C11 and C13 is connected to the input terminal via switch B. At the same time, the short circuit is given to capacitors C12 and C13 via switches B2 and B1, and capacitor C11 is connected to the input end of integrating circuit M formed by circuit A via switch B2. In such way, the device can be formed in the monolithic way onto the semiconductor substrate and with a miniature size and high density regardless of a large integration constant of the device.
