The Synchrotron Radiation Source (SRS) at Daresbury Laboratory has a 600MeV Booster, fed by an energy storage power supply configuration (White Circuit). The design consists of two power supplies : an AC source to supply the losses to the parallel resonant circuits and a DC supply to fully bias the AC sinewave. In a recent modernisation of the control electronics, different methods of achieving...

We demonstrate a novel algorithm for assigning the threshold voltage to the gates in a digital random logic complementary metal—oxide—semiconductor (CMOS) circuit for a dual-threshold voltage process. The tradeoff between static and dynamic power consumption has been explored. When used along with device sizing and supply voltage reduction techniques for low power, the proposed algorithm can re...

In the field of analog signal processing, there is a strong need for low-voltage and low-power integrated circuits. Especially in the mobile communication circuitry, an analog signal processing circuit must be fed by dry batteries of 1–1.5 V. This paper presents a design and implementation of a current-mode fully-differential analog CMOS integrator operable with such a low supply voltage. This ...

This paper demonstrates an on-chip di/dt detector circuit. The di/dt detector circuit consists of a power supply line, an underlying spiral inductor and an amplifier. The mutual inductor induces a di/dt proportional voltage, and the amplifier amplifies and outputs the value. The measurement results show that the di/dt detector output and the voltage difference between a resistor have good agree...

In this paper, we implement a circuit topology for the gold standard ATX80+.The total output power is 255 watts under full load operation. An active-clamping ZVS forward converter is adopted to provide main power and in secondary side, the BUCK circuit technology is adopted to provide 3 sets power +12V, +5V and +3.3V. To eliminate the current harmonics and to achieve high power factor, an activ...

A Delay (D) flip-flop is an edge triggering device. A high speed, low power consumption, positive edge triggered conventional Delay (D) flip-flop can be designed for increasing the speed of counter in Phase locked loop, using 32nm CMOS technology.
