IPC: G11B20/02
Filed: 1990-11-24
Abstract: PURPOSE:To extract a required band signal as the same level naturally independently of the level of an input signal by providing an automatic level control circuit and a level correction means controlling the level in opposite direction to the control of the automatic level control circuit before and after a filter circuit. CONSTITUTION:The device consists of an automatic level control circuit 2, a filter circuit 55 and a level correction means 8. In such a case, since the level of an input signal limited by the automatic level control circuit 2 in advance, the level is inputted to the filter circuit 55 as a level in matching with the dynamic range of the filter circuit 55 and the filter characteristic is not deteriorated. Moreover, the output of the filter circuit 55 is subjected to control in opposite direction to that by the automatic level control circuit 2 by the level correction means, a similar level change to that of the input signal is obtained. Thus, it is equivalent that the signal resulting from eliminating a signal at noise or an undesired frequency band from the input signal is outputted from the filter circuit 55.

Abstract: PURPOSE: To provide a drift electric field for accelerating a carrier in a base layer and thus increase the speed of operation, by having a structure to generate an internal piezoelectric field from a collector layer side to an emitter layer side in the base layer. CONSTITUTION: On a substrate 1 which is a semiconductor of zinc-blende crystal structure and has a crystal plane having electric polarity as a main surface thereof, a base layer 4 having compression or tension strain is grown by epitaxial growth.

This piezoelectric field functions as a drift electric field for electrons as minority carriers in the base layer, thus accelerating the electron speed and shortening the base transit time. In addition, by inclining a mixed crystal composition on the side of the emitter layer 5 and the side of the collector layer 3, an inclination of energy potential for electrons is generated in the base layer 4 having strain.  The inclination functions as a drift electric field, thus accelerating the electron speed and shortening the base transit time.
