Abstract
1,109,891. Frequency modulation. MULLARD Ltd. 10 March, 1966 [10 March, 1965], No. 10183/65. Heading H3R. A circuit for simulating reactance comprises an insulated gate field effect transistor 5, e.g. a MOST, with a series circuit comprising a capacitor 2 and resistor 1 connected between the sink and source electrodes, and the junction of the capacitor and resistor being connected to the gate. The Q of the circuit is improved by the inclusion of a further CR network 6, 7. In a modification, Fig. 1, of the drawing accompanying the Provisional Specification (not shown) this CR network is omitted and it is stated that the resistor 1 may be a further field effect transistor and that the capacitor 2 may be shunted by a resistor to modify the bias point of the transistor 5. In further embodiments, Figs. 1, 2 of the drawings accompanying the Complete Specification (not shown) a tetrode MOST is used in place of the MOST 5, the additional gate being connected to a bias circuit.
