Multiple purpose hybrid film circuit for active filters - consists of array of resistors and capacitors which can be connected in many different ways for different filters

摘要

The circuit using film technology, contains an operational amplifier, which can be connected in different ways to form RC active second order transfer function filters with varying characteristics. The circuit consists of a number of resistances and capacitances constructed in film technology on a single chip, with an operational amplifier connected in one of two possible positions on the chip. The array of components is such that by connecting the terminals in different ways and by mounting the operational amplifier appropriately, a large number of filter circuits can be constructed.
