The ATTA project has been created in order to laser cool and count single atoms of low level krypton contamination in xenon, motivated by the XENON Dark Matter program. An important component of the ATTA system is the laser, and its linewidth must be smaller than that of the atomic transition of the krypton atom to be trapped. An experiment was developed in order to measure this linewidth. A dr...

We describe a new design technique for efficient harmonic resonant rail drivers. The proposed circuit implementation is coupled to a standard pulse source and uses only discrete passive components and no external dc power supply. It can thus be externally tuned to minimize the consumed power in the target IC. A new design technique based on current-fed voltage pulse-forming network theory is pr...

Piezoelectric transducers are known to exhibit less hysterisis when driven with current or charge rather than voltage. Despite this advantage, such methods have found little practical application due to the poor low-frequency response of present current and charge driver designs. This paper introduces the compliance feedback current driver containing a secondary voltage feedback loop to prevent...

A very simple circuit design of a bidirectional input/output(I/O) buffer is proposed for mixed voltage interface applications. By a floating N-well circuit technique two series PMOS transistors are used as an active pull-up driver. Such a structure provides a simple circuit that requires only a single terminal pad, a single power supply, and is free of DC leakage current. Mixed voltage interfac...

Temperature management and control are among the most critical functions in power electronic devices. Knowledge of power semiconductor’s operating temperature is important for circuit design, as well as for converter control. Virtual junction temperature measurement or estimation is not an easy task, therefore designing the appropriate circuitry for virtual junction temperature in the real oper...

This paper presents an area-effective bandwidth enhancement technique using interwoven inductors. Inductive peaking is a common practice for bandwidth enhancement, however the area overhead of inductors is a serious issue. We implement six or four inductors into an interwoven inductor. Furthermore parasitics of the inductors can be reduced. The proposed inductor is applied to a laser-diode driv...

A novel single-stage push–pull electronic ballast with high input power factor is presented in this paper. The proposed electronic ballast combines the front-end power-factor corrector and push–pull converter into a single-stage converter. Compared to the single-stage class-D electronic ballast, the proposed circuit does not require an isolated driver. The control of the circuit is easier and t...

This paper presents a mixed-signal LVDS driver in 90 nm CMOS technology. The designed LVDS core is to be used as a data link between Infrared Focal Plane Array (IRFPA) detector end and microprocessor input. Parallel data from 220 pixels of IRFPA is serialized by LVDS driver and read out to microprocessor. It also offers a reduced power consumption rate, high data transmission speed and utilizes...

With the advent of reliable, high brightness and high efficacy LEDs, the lighting industry is expected to see a significant growth in the near future. However, for LEDs to completely replace the traditional incandescent and CFL bulbs, the power converters within the LED drivers need to be miniaturized. Superior figure of merit (Rds,ONxQg) of Gallium Nitride (GaN) FETs over Silicon FETs [1] can ...
