    • PROBLEM TO BE SOLVED: To provide a boosting type level shifting circuit with the improved hot carrier robustness. SOLUTION: A series circuit of resistance elements R106_a and R106_b is arranged between each of the drains of a transistor Q101 at an input stage and a transistor Q103 at an output stage. The series circuit is also used as a feedback signal acquiring portion 105. A signal acquired by a connection node N106 of one of resistance elements R106_a and R106_b is adopted as a feedback signal SFB to the gate of the transistor Q103 of another side at the output stage. When the resistances element R106_a and R106_b are arranged as above, voltage between the drain and the source of the transistor Q101 can be reduced to a small value by utilizing potential difference based on an operating current at the time of switching operation, thereby, the hot carrier robustness can be improved. In addition, since a positive feedback loop from a shallow voltage level of the connection node N106 can be formed, a quick response can be obtained. Since a pinch-off region can be quickly got through, the hot carrier robustness can be improved. COPYRIGHT: (C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a differential output circuit capable of preventing generation of common-mode noise, and to provide a communication device. SOLUTION: This differential output circuit includes first and second current mirror circuits 11, 12 that provide the gates of slave-side transistors Q12, Q14 with gate voltages of master-side transistors Q11, Q13 via voltage followers A11, A12 where a slew rate at a rise time is equal to that at a fall time. Thus, when the master-side current is increased or decreased by providing the gates of the slave-side transistors Q12, Q14 with the gate voltages of master-side transistors Q11, Q13 via the voltage followers A11, A12 where the slew rate at a rise time is equal to that at a fall time, an incremental change in slave-side current and a decremental change in slave-side current are made symmetrical with each other. The use of such current mirrors in a differential manner leads to no generation of common-mode noise even in these changes. COPYRIGHT: (C)2010,JPO&INPIT
