Title: Ic for driving light emitting diode array with current control function
Inventor: YAMADA ATSUSHI
IPC: H05B44/00
Filed: 1985-09-18
Abstract: PURPOSE:To control driving current of an LED array for each driving IC easily and facilitate correction of temperature characteristics inside the IC by a method wherein resistances are connected between power sources and the potential of the optional intermediate point is used as a power source for a source of an N-channel type MOS transistor (TR) and the plus source is used as a power source for a source of a P-channel type MOS-TR. CONSTITUTION:If a voltage V0 is applied between a VDD terminal 6 and a VSS terminal 9, a voltage divided by resistances R1, R2 and R is induced at a CTL terminal 8. As this voltage is a power source for a source of an N- channel type MOS-TR 4, a gate voltage under an ON state of an output TR 5 is given through a CMOS inverter, which is constituted by a P-channel type MOS-TR 3, whose gate input is an output control signal 7 which controls ON- OFF states of the output TR 5, and an N-channel type MOS-TR 4. An output current ID can be controlled by changing the value of an external resistance R. Therefore, by regulating the value of the external resistance R of each IC chip for driving each LED array, the driving current can be controlled in accordance with luminance characteristics of the connected LED array.

Abstract: PURPOSE:To decrease a resistance conventionally inserted to a signal line from several tens kOMEGA to several tens OMEGA and to improve the attenuation from a conventional value of 60dB into nearly 120dB considerably by using two variable mutual conductance amplifiers. CONSTITUTION:A sound signal from a sound signal source 1 is outputted to a variable mutual conductance amplifier 7, and in this case, an output current I7 proportional to the output of a variable voltage source 6 is supplied to a variable control input terminal of the amplifier 7 from a variable current control circuit 10 and the output impedance of the amplifier 7 is 1/gm(7). Moreover, an output current I8 inversely proportional to the variable voltage source 6 from the variable current control circuit 10 is fed to a variable control input of the variable mutual conductance amplifier 8. The relation of the output currents I7, I8 is expressed as I0-I7=I8 with respect to a reference current source I0 and when the output current I7 is increased, the control is applied to a variable current control input terminal 4 so as to decrease the output current I8. Thus, the signal Vin inputted from the input terminal 2 is attenuated by the variable mutual conductance amplifiers 7, 8 and outputted from an output terminal 3 via the buffer amplifier 9.
