Abstract
1467126 Automatic current regulation PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 March 1975 [11 March 1974] 9573/75 Heading G3X An arrangement for stabilizing a current with respect to temperature variations includes a first circuit with input, output and common terminals producing at its output a current with a negative temperature coefficient. A second circuit, having two terminals connected respectively to the output and common terminals of the first circuit, carries a current which has a positive temperature coefficient arranged to compensate for first order temperature effects. The input and output currents of the first circuit are connected to respective terminals of a circuit having two branches in which the currents are in a fixed ratio, independent of temperature and voltage. As shown in Fig. 3. a current mirror T7, T8, T9 supplies current to the input A of a three-terminal circuit, Fig. 1, which produces an output current I1 at terminal A’ with a negative temperature coefficient. The input terminal G’ of the current mirror is also connected to one terminal C of a twoterminal network, Fig. 2, with a positive temperature coefficient of current. Resistors R1, R2 are chosen so as to balance the temperature coefficients to the first order. A current squaring circuit, Fig. 4 (not shown), may be included in the arrangement, Figs. 5-6 (not shown), if second order compensation is required. The arrangement may be constructed as a monolithic integrated circuit and used to supply a frequency-stable oscillator or a digitalto-analog converter.
