Circuit for storage of bipolar currents consisting of two basic storage circuits, one with N MOS and another with P MOS transistor contg. current storage cell

摘要

From one current storage basic cell transistors (102,101) is obtained a factor-graduated copy of the storage current, from which then a rated current is subtracted by a unit (103). The differential current energises the respective other basic cell by a current-voltage converter (104). The subtraction operation unit, the current-voltage converter, and the basic cell P MOS transistor (101) form a control loop, controlling the drain current of storage transistors at an input current from zero to a defined rated value. Input currents, exceeding the rated value, are stored in the cell with N MOS transistor (102). Otherwise they are stored in the cell with P MOS transistor.
