This article presents the design of a driver system for vertical cavity surface emitting lasers (VCSELs), including limiting amplifier, delay circuit, driver circuit and 5-bits DAC. By adding a delayed pulse on the original data signal, the VCSEL driver adopts a new method to compensate the ringing generated by the bound-wire inductance, pad capacitance and VCSEL. Through adjusting the delay time,...
This paper presents a power efficient static frequency divider (SFD) for wideband operation. Series inductive peaking technique is utilized to construct broadband input network of the divider. The aspects of design using the technique are supported with exhaustive simulations. The prototyped divided-by-two frequency divider is implemented in 65 nm LP CMOS technology. Measurement results show that...
Dielectric Barrier Discharge (DBD) with catalyst can remove NOx effectively from diesel exhaust gas, the solid catalyst particles in the type of one section DBD reactor can play the role of barrier, lead to improve the discharge power effectively. The effect rule of the particle diameter which filled in the DBD reactor on the discharge power is studied by establishing mathematical model and testing...
