IPC: H01L21/82
Filed: 1992-01-28
Abstract: PURPOSE:To control noise generated at the time of operation of an output buffer without changing the design of the output buffer. CONSTITUTION:An output buffer 1, 1a is divided to a front stage inverter 2, 2a constituted of internal cells 5 and a back stage inverter 3, 3a constituted of peripheral cells 6 and the wiring length of a wiring 4, 4a which connects the front stage inverter 2, 2a and the back stage inverter 3, 3a is controlled according to the location where the front stage inverter 2, 2a is located. By this, the output load of the front stage inverter 2, 2a is determined and the unclearness of an output wave form of the front stage inverter 2, 2a is adjusted. Since a noise generated at the time of operation of the output buffer 1, 1a depends on the unclearness of an input wave form of the front stage inverter 3, 3a, it is possible to control the noise by controlling the wiring length of the connection wiring 4, 4a.

Abstract: PURPOSE:To ensure an automatic exclusion of the beat component due to the disturbing frequency in accordance with the amount of the beat component, by detecting the signals having the levels in a prescribed range including the beat component due to the disturbing frequency and then filtering the disturbing frequency in accordance with the output of detection. CONSTITUTION:In case the station that receives an effect of the disturbing frequency of the carrier wave of the adjacent station is received, the level signals within a prescribed range including the beat component due to the disturbing frequency are extracted through the band pass filter 9. The extracted signal is amplified by the amplifier 10 and receives a wave detection through the wave detection circuit 11 to be applied to the transistor 13 and the doide 14. Then the current flowing to the transistor 13 and the diode 15 varies by the current flowing to the diode 14. In other words, the resistance value of the diode 15 varies according to the detected signal level of the disturbance frequency. As a result, the filtering quantity of the notch filter 20 that filters the disturbing filter varies in accordance with the signal level of the disturbing frequency.
