ELECTRIC CIRCUIT OF LOW CURRENT CONSUMPTION

摘要

PURPOSE:To obtain an electric circuit having a reduction of current consumption as a whole by dividing an analog or digital electric circuit into some parts and applying the DC power supply voltage of a high level to the electric circuit for actuation to share the current consumption of each divided circuit part. CONSTITUTION:It is supposed that the current consumption of a partial circuit C3 is equal to or larger than those of partial circuits C1 and C2. Under such conditions, an input signal is supplied from a terminal 4 to pass through successively the input/output terminals of circuits C1-C3 and reaches an output terminal 5. Then a comparison is carried out with the power consumption when the external voltage supplied to an electric circuit is higher than E-volt and the circuit is actuated after converting the external voltage into E-volt by a series regulator. In other words, the power consumption of a conventional circuit is set as P0=E0(I1+I2+I3) in the case E0>3E (E0: input voltage of the regulator). Thus the power consumption of this circuit is set as P1=E0.I3
