    Abstract: Each starved-inverter of a voltage controlled ring oscillator has an output transfer gate associated therewith. The pair of complementary switches composing a transfer gate being controlled in common with the relative current generators of the starved-inverter stage, by a frequency control voltage and by a voltage difference between a supply voltage and the control voltage, respectively. The frequency produced by the oscillator is linearly proportional to the control voltage and inversely proportional to the square root of the supply voltage, for an enhanced noise immunity and improved frequency stability.

    Abstract: A latch circuit that is intentionally unbalanced, so that a first output reaches ground voltage and a second output reaches a supply voltage. The latch circuit may be used with a fully static low-consumption fuse circuit which reverses the first and second outputs of the latch circuit when the fuse is in an unprogrammed state, but does not change the outputs of the latch circuit in the programmed state. In particular, the latch circuit has a first transistor of a first polarity series connected at a first output node with a second transistor of a second polarity between a supply voltage and a ground voltage. A third transistor of the first polarity is series connected at a second output node with a fourth transistor of the second polarity between the supply voltage and the ground voltage. The gate terminals of the first and second transistors are connected to the second output, while the gate terminals of the third and fourth transistors are connected to the first output. The first and third transistors have thresholds which are mutually different, and the second and fourth transistors have thresholds which are mutually different, so that the first output reaches ground voltage and the second output reaches the supply voltage. This circuit can be combined with a fuse circuit, such as a dual gate transistor.

    Abstract: A method for loading the content of any selected cell of a source register to any selected cell of a destination register. The value in the selected source cell is tested for a value of zero. The value of the destination register is then copied into a temporary register. During the copying, the selected destination cell is set to a selected value. The selected destination cell, in the temporary location, is either left unchanged or reset to a complementary value depending on the result of the previous zero test. In either event, the value of the temporary register is then copied to the destination register.

    Abstract: Power consumption by the driving circuitry of an output stage, employing a slew-rate controlling operational amplifier, is reduced by modulating the level of the current output by the operational amplifier in function of the working conditions of the output stage. Switching delay may also be effectively reduced. An auxiliary current generator forces an additional current through the conducting one of the pair of input transistors of the operational amplifier only during initial and final phases of a transition, essentially when the slew rate control loop ceases to be effective. The boosting of the bias current through the conducting input transistor is determined by the degree of unbalance of the differential input stage of the operational amplifier, without the use of dissipative sensing elements.

    Abstract: A power stage of quasi-complementary symmetry, including a common-source FET and a common-drain FET, with a reduced absorption of current under the conditions of high impedance of the output. The driving node of the upper (common-drain) transistor from is decoupled from the output node of the stage, preventing the current generator Id, which discharges the control node, from absorbing current from the load connected to the output stage, during a phase of high output impedance. This is preferably realized by using a field effect transistor which has its gate connected to the output node of the stage, and is connected to provide the current drawn from the discharge generator of the driving node of the upper common-drain transistor, absorbing it from the supply node VDD instead of absorbing it from the voltage overdriven node Vb. This alternative solution avoids excessive loading of the high-voltage supply, and is particularly useful when the overdriven node Vb drives multiple output stages.
