Abstract:
A non-inverting gallium arsenide depletion mode latch circuit is responsive to high and low input data, and to clock pulses from a clock having high and low pulses for loading data and for translating data from the input to the output in a single gate delay. The circuit includes a pair of pull-up FETs having their conduction paths connected in parallel with an output node in circuit with the FETs for output data. A positive feedback path is enabled from one of the FETs for reinforcing the data at the output node. The one FET enables the feedback path during clock pulses in the low direction, while the other FET applies data to the node during high clock pulses. Data input FETs enable and disable the other FET in accordance with the input data and selective clock pulses, while a clock pulse input FET enables and disables the one FET in accordance with the clock pulses.
Abstract:
A CDCFL latch circuit having a plurality of inputs and first and second outputs includes a gate circuit responsive to logic input signals supplied to the plurality of inputs for providing complementary output logic signals at the first and second outputs when the gate circuit is rendered operative. A regeneration circuit is coupled to the first and second outputs for maintaining the complementary output logic signals at the first and second outputs when the regeneration circuit is rendered operative and the gate circuit is rendered non-operative. A shared load circuit provides current to the gate circuit when the gate circuit is operative and for providing current to the regeneration circuit when the regeneration circuit is operative. A control circuit responsive to a complementary clock signal and coupled between the shared load circuit and the gate and regeneration circuits alternately renders the gate circuit operative when the complementary clock signal is in a first logic state and the regeneration circuit operative when the complementary clock signal is in a second logic state.
Abstract:
A latch circuit has first to fourth nodes. The first node is supplied with a logic signal and the second node is charged at a first potential. A potential at the third node is discharged to the second potential. The fourth node is charged to the first potential. This all happens during a first period, after which, and during a second period, a potential at the second node is transferred to the third node. An inverter transistor is responsive to a level of the logic signal at the first node for discharging a potential of the second node to a second potential when the logic signal level is in the first potential and for retaining the first potential of the second node when the logic signal level is in the second potential. A transfer between the fourth and the first nodes is responsive to the second potential at the third node for discharging the potential of the fourth node to the second potential. A true and a complement signals of a large amplitude are established at the fourth and second nodes.

A memory-array sense amplifier includes a grounded-gate depletion-mode FET connected between a bit line and a sense node. Another FET connects a supply voltage VDD to the sense node when turned on by a clock phase signal. Further FETs form a latch circuit.
Abstract:
A balanced differential circuit is provided which is useful as an address buffer in digital memories. The circuit is illustrated as a single ended input circuit having complementary outputs. Capacitors are used to couple imbalancing signals into the circuit. Through selective timing of load devices within the circuit power dissipation is kept to a minimum.
Abstract:
The voltages to be compared are applied to a passive MOS capacitor differencing circuit for producing a voltage difference signal, which then is amplified by a high-gain non-precision FET amplifier, the output of which is passed through a low output impedance FET buffer amplifier to a FET latching circuit. Capacitive coupling is used for enabling the amplifiers to be independently biased and to eliminate D.C. offsets. The operating cycle of the comparator has two periods. During an initial set-up or preconditioning period the amplifiers are self-biased by appropriate switching actions which cause each of the amplifiers to be set at a desired operating point that is maintained when its respective bias switching connection subsequently is opened. The bias switch openings in the respective amplifier and latching stages are timed to occur in a chosen sequence which causes the switching transients to be absorbed. At the end of the preconditioning period, the comparator is set up for operation in the comparison period during which the input signals are compared.
Abstract:
An amplifier circuit for amplifying an input signal includes a flip-flop circuit activated by a timing signal. A trigger circuit generates a first trigger signal of the same polarity as the input signal and another circuit generates a second trigger signal of the opposite polarity to the input signal. The flip-flop circuit is triggered by the first and second trigger signals at the same time the flip-flop circuit is activated by the timing signal.

The third MISFET is rendered non-conductive and the sixth MISFET conductive at writing when at least the fourth and eighth MISFET''s are conductive.
