Abstract: PURPOSE:To reduce the consumed power of a C-MOS inverter or the like, by providing a current limiter of constant current characteristic between a switching element and a power source so that the charging and discharging currents of a capacitive load are almost equalized to each other. CONSTITUTION:An enhancement-type p-channel MOSFET18 is connected between a power source anode VDD and another enhancement-type p-channel MOSFET12a which constitutes a C-MOS inverter 12. An enhancement-type n-channel MOSFET 19 is connected between another enhancement-type n-channel MOSFET12b and a power source cathode (the ground). A constant voltage VGS1 is applied across the gate and source of the FET18. Another constant voltage VGS2 is applied across the gate and source of FET19. These voltages are set equal to each other so that the FET's 18, 19 are operated as constant current sources of almost equal characteristic. A crystal oscillator circuit 11 or the like is thus constituted. As a result, a charging current flowing from the power source anode VDD into a floating capacitance 25 and a discharge current flowing out to the ground are equalized to each other and a transient penetrating current at the inverting action of the inverter 12 is limited below a prescribed level to reduce consumed power.

Title: Mutual conductance amplifier
Inventor: ROBAATO ARAN BUROUSHIRUDO
IPC: H03F1/32
Filed: 1982-02-10
Abstract: A transconductance amplifier includes a differential transconductance amplifier stage (10, 11) and a differential correction amplifier stage (18, 19). In order to achieve substantially linear operation over a wide dynamic range, the effects of nonlinearities in the transconductance amplifier stage are substantially cancelled by the effects of nonlinearities in the correction amplifier stage. This is accomplished by cross-coupling the two stages and establishing the relative gain of the correction amplifier stage with respect to the transconductance amplifier stage such that the desired cancellation occurs. In a preferred embodiment, optimum cancellation occurs when the gain of the correction amplifier stage is substantially one-half the gain of the transconductance amplifier stage.
