Definitions
- FIG. 1 shows a first exemplary embodiment of the electronic circuit with four resistors
- FIG. 2 shows a second exemplary embodiment of the circuit with a resistor and two switches
- Figure 3 shows a third embodiment of the circuit with thyristors and a shift register.
- This circuit is provided in particular as an integrated circuit, wherein individual by controlled melting through fuses Q0, Q1, Q2, Q3, different values are set for the total measurable between the terminals A, B total conductance Y. Circuits of this type are used in particular when it is not yet possible to precisely set a conductance or resistance at the time the circuit is being designed or constructed. In the case of integrated circuits, which are surrounded by a housing, a melting through can occur, particularly in the case of integrated circuits zelner fuses Q0, Q1, Q2, Q3 still set a resistance after installation in a housing. Thus, circuits influenced by the housing can be adjusted so that the influence of the housing is compensated or minimized.
