Title: Semi-Conductor Drift Field Delay Line for Use in Tunable Signal Translation Systems
IPC: H01L29/00
Filed: 1967-08-08
Abstract: 1,150,526. Transistor pulse and amplifier circuits. WESTINGHOUSE ELECTRIC CORP. 8 Aug., 1967 [26 Aug., 1966], No. 36335/67. Heading H3T. [Also in Division H1] A frequency selective amplifier, oscillator or delay circuit includes a semi-conductor delay line (see Division H1) which consists of an elongate semi-conductor body 17 with two rectifying contacts 16, 18 and two ohmic contacts 51, 52, the former of which is in two parts 51a, 51b which are connected together. The transit time of minority carries between electrodes 16 and 18 is controlled by the potential difference between ohmic contacts 51 and 52 and, because the potential gradient adjacent the emitter 16 is maintained at zero by the shortcircuit between contacts 51a and 51b, the tendency of minority carriers injected at the emitter to distort the drift field set up by the potential applied between contacts 51 and 52 is minimized. The delay line is incorporated in a phase-retarding feedback loop between the input and output of the amplifier constituted by transistors T1 and T2 and their associated circuitry. For a particular frequency the phase retardation is 360 degrees and if the amplifier gain exceeds the delay line loss the system will oscillate at this frequency. At lower gains the system is effective as a band-pass filter. The operating frequency is controlled by the potentiometer 54, which varies the drift field and hence the transit time of minority carriers. The control characteristic, because of the minimization of distortion achieved by the short-circuited contacts 51a and 51b, is substantially linear.
