An analog UV-light programmable voltage reference implemented in CMOS technology is programmed by exposing UV-structures to ultraviolet light. The voltage reference comprises two UV-structures provided between respectively each supply line and a floating node connected to the gate electrode of a field-effect transistor for detection of the voltage of the floating node. The voltage of the floating node is stabilized on a value determined by the voltages of the UV-structures, the capacitance of the floating node being given by the sum of the capacitance of the UV-structures, the capacitance of the gate electrode and possible parasitic capacitances. The analog voltage reference is used for implementing respectively an analog voltage adder, analog amplifiers with either increased linear input range or accurately determined amplification, as well as a UV-light programmable analog memory. A method of programming the analog memory is disclosed. |
