Abstract: A stabilized control voltage, suitable for supplying operating bias to a direct current coupled amplifier forming part of an integrated circuit of cascaded amplifier stages, is provided by the circuit arrangement shown in which the voltage at output terminals 46, 52 is determined by the voltage at input terminals 42, 46, by the number of transistors 30, 32, 34, 36, by the values of the resistors 44, 48 and by the number of semiconductor diodes 45, 47, 49, 51, the transistors, diodes and resistors being provided in a single integrated circuit whereby the respective diode forward voltage drops and transistor V be voltages are identical and the ratio of the resistors 44, 48 is invariable. As a result the voltage at output terminals 46, 52 is independent of temperature variations and is equal to 1/N + 2 times the voltage at input terminals 42, 46, where N represents the number of stages of transistor coupling between transistors 30, 32, where the value of resistor 44 is N + 1 times the value of resistor 48 and where the number of diodes in the collector connection is N + 1 times the number in the emitter connection. An arrangement using two transistors, two diodes and equal value resistors is described, Fig. 1 (not shown) and a theoretical analysis is given for this arrangement and for that of Fig. 2. If desired the control voltage may be taken from terminals 42, 52, in which case it is equal to N + 1 / N + 2 times the voltage at input terminals 42, 46. The two transistor arrangement may be used to establish and maintain the operating point of a known amplifier circuit comprising an emittercoupled amplifier stage driving a common collector stage, Fig. 3 (not shown), both the arrangement and amplifier being formed on a single semiconductor body comprising a portion of an integrated circuit chip providing a multi-stage direct coupled amplifier.

Patent ES-467726-A1 (ES)
Title: Low reactivity penalty burnable poison rods
IPC: G21C7/04
Filed: 1978-03-09
Abstract: A rod which contains a burnable neutron absorber material (40) is used for the initial compensation of excess reactivity present in the reactor core. Such a burnable neutron absorber rod (22) is constructed such that it also contains a moderator, at least when operating, for example by arranging for the primary coolant, which serves simultaneously as moderator, to flow through the cladding (24, 30). This results in increased neutron moderation in the region of the neutron absorber rod, which accelerates the depletion of the neutron absorber during the operating time. It is achieved as a result that after decrement of the excess reactivity, the neutron absorber is also consumed and thus its neutron poisoning effect is cancelled, so that the service life or the degree of burn-up of the reactor core can be improved.
