摘要： A circuit for limiting the transitory's overvoltage across a power transistor connected essentially in series with an inductive load between a supply rail and a ground rail of the circuit and operated to switch ON-OFF said inductive load utilizes a comparator circuit for switching-ON again the power transistor in order to discharge the energy stored in the load's inductance. The voltage across the power transistor is sensed by a first voltage divider, while a reference voltage is obtained by means of a second voltage divider connected between the supply and ground. The circuit is practically insensitive to temperature and to variations of the supply voltage and is easily implemented.

摘要： A power-on reset circuit employs a supply voltage sensing line (M1,R1,R2,M2) for triggering a first inverter (M3,M4) of a pair of cascaded inverters (M3,M4;J). The intrinsic static consumption of such a POR circuit is strongly reduced by employing a current generator (G1,G2,R3), which is automatically forced to deliver a reduced current during the operation of the integrated circuit, for biasing two transistors functionally connected in said voltage sensing line (M1,R1,R2,M2) into a subthreshold operating condition.

摘要： A static, edgetriggered, D flip-flop has the second (feedback) inverter of each latch of the flip-flop structure formed by four field effect, complementary-by-pair, transistors (MP1, MN1, MP2, MN2), functionally connected in series between the supply nodes. A first pair of complementary transistors (MP2, MN2) having a source connected to one and the other supply nodes, respectively, have a gate which is connected to the supply node of opposite sign as referred to the sign of the supply node to which the respective source is connected. The other pair of complementary transistors (MP1,MN1) Have their drain connected in common to the output node (A) of the inverter, a gate connected to the output node of the first (forward) inverter (I) of the latch, and a size which is essentially smaller than the size of said first pair of complementary transistors (MP2, MN2).
