Definitions
- One embodiment of the invention provides for at least one second auxiliary transistor to be connected in parallel with the first auxiliary transistor and to be controllable via the second control connection.
- the at least one second load transistor and the at least one second auxiliary transistor form a second transistor pair in accordance with the first transistor pair. If further air transistors are provided, further transistor pairs are formed by providing further auxiliary transistors, with each load transistor preferably being supplemented by an auxiliary transistor to form a transistor pair.
- the second auxiliary transistor which is also connected to the second input terminal of the measuring arrangement with a first load path connection, maps the load path current flowing through the second load transistor to the measuring current.
- the load R is to be connected, at least one of the control connections Gl, Gn is connected to the upper control potential V ++.
- the number of load transistors TU, Tln to be controlled depends on the current flowing through the load! ⁇ __, the control circuit ASS being connected to the output terminal AK of the measuring arrangement MA for evaluating this current I L flowing through the load.
- the upper control potential V ++ is preferably greater than the supply potential V + and can be provided, for example, by a fixed voltage supply or generated from the supply potential V + by means of a charge pump circuit.
