Abstract
1330096 Transistor amplifying circuits THOMSON-CSF 4 April 1972 [6 April 1971] 15550/72 Heading H3T A phase corrector includes an output adder 4, Fig. 1, having two inputs 41, 42 coupled to the input 20 of the phase corrector, one, 42, through a device which gives a voltage qVe where q is a real number and Ve the input voltage of the phase corrector, the other, 41, through an amplifier 1 having a load constituted by a parallel resonant circuit the three parallel branches of which are respectively formed by an adjustable capacitor 3, an adjustable inductance 2 and a fixed damping resistor R, the complex gain G of the amplifier being equal to mZ<SP>1</SP>/R where Z<SP>1</SP> is the impedance of the damped resonant circuit and where m is equal to - 2q. In this embodiment, the device comprises equal resistors 10, 11 and resistor 12 is equal to resistor 13 in value: in a second embodiment (Fig. 2, not shown) resistor 13 has twice the value of resistor 12 and the input 42 is derived directly from terminal 2 0. The adder 4 comprises two transistors 44, 45, Fig. 3, having equal emitter circuit resistors 46, 47 and with their collectors connected together, the two bases comprising terminals 41, 42 respectively.
