Abstract
A low-power consumption, high-speed electronic switching system has a pair of complementary switching means connected between opposite polarity terminals of the voltage source and an output terminal. The pair of switches provides a variable impedance for applying one or the other of the polarities and said output terminal. To speed an appearance of that polarity, an inverter is coupled between an input and an output terminal via a differentiating capacitor. The differentiated inverter output speeds the appearance of the switched output signal during the interval before the complementary input becomes effective thereat.

A transistor circuit comprising:
- a. a first variable impedance element for changing its impedance in response to an input signal;
- b. a second variable impedance element for changing its impedance in response to said input signal, said second variable impedance element being connected in series to said first variable impedance element, the change in impedance of said second variable impedance element being opposed to the change in impedance of said first variable impedance element with respect to said input signal;
- c. an input terminal for receiving said input signal, said input terminal being coupled to said first and second variable impedance elements to vary their impedances;
- d. an output terminal deriving an output signal in response to said input signal, said output terminal being connected to means for coupling both said first and second variable impedance elements;
- and
- e. means coupled between said input and output terminals for differentiating said input signal.
A low-power consumption, high-speed, electronic voltage level switching system comprising a pair of variable impedance complementary switching means having control electrodes connected to a common input terminal, whereby said complementary circuit switches an output terminal back and forth between two conductive states responsive to changes in polarity of input signals appearing at said input terminal, first means for differentiating said input signals, and second means for applying the output of said first means to said output terminal.
A method of switching an output terminal of an integrated semiconductor current between two opposite polarities, said method comprising the steps of:
- a. driving a complementary circuit responsive to input pulses of opposite potentials, whereby one side of said complementary circuit is conductive and the other side is non-conductive at the same time;
- b. driving an inverter responsive to said input pulse;
- and
- c. applying an output of said inverter via a capacitive coupling means to said output terminal thereby speeding an appearance of the polarity of the output of said inverter at said output terminal.
