Title: Demodulator circuit
Inventor: KUROGAMI YUUZOU
IPC: H04B1/10
Filed: 1993-06-18
Abstract: PURPOSE:To provide a demodulator circuit capable of stably executing gain control for a modulation signal without malfunction even if rader pulse interference occurs. CONSTITUTION:A rader pulse detector(DETECT) 16 monitors a digital demodulation signal outputted to an output terminal 2 and detects the generation of a rader pulse. When the rader pulse generates a gain controller (AGC-CONT) 14' sets up the signal level of a gain control element signal S1 to be outputted to an integrator (integral ) 15 to '0' to prevent the gain of a gain controller(AGC) 11 from being varied. When the rader pulse is interrupted, the AGC-CONT 14' generates the signal S1 again to send a gain control signal S2 smoothened by the integrator (integral ) 15 to the AGC 11. Consequently the AGC 11 executes gain control so as to output a normal digital demodulation signal from an output terminal 2.

Filed: 1980-10-22
Abstract: PURPOSE:To reduce the power consumption and to prevent an erroneous read-out operation caused by incoming of a noise signal, by constituting a pair of transistors on the final stage connected to an address line, of an enhancement type, and further providing a transistor switching circuit. CONSTITUTION:When a decode output AN is a low level, a transistor TR switching circuit 41 is turned off, and a driving TR36 is also turned off. A TR37 is in an on-state, however, the potential of an address line 33 is ground potential and becomes a non-active state. In this case, to the TR36, only a leak current flows, and even if a noise comes in the line 33, memory cell TRs 341-34m are not driven. On the other hand, when the line AN becomes a high level, the TR37 is turned off. In this case, the TR36 is an on-state, and the line 33 becomes an active state. In this  since the TR36 is an enhancement type, a driving current required for operating an  ROM cell 32 at a high speed is not obtained enough, but the driving current flows  to the line 33 through a TR40, and a driving current required for a high speed  operation is obtained.
