A new high performance second-generation CMOS current conveyor architecture is presented. It is built using a differential flipped voltage follower as its input buffer stage and a cascode current mirror as output stage. It is characterized by very low output impedance. It provides gain independent high bandwidth when used to implement a programmable gain voltage amplifier. Simulation and experi...

This paper explores a sensorless technique for orienting planar parts. We follow an approach described in earlier papers [3, 4] called 1JOC for One Joint Over Conveyor, which can perform planar manipulation using a single controlled joint in combination with a constant-velocity conveyor. Our previous work demonstrated that the 1JOC approach can orient and feed planar polygonal parts, given a si...

given by (6) can successfully shorten the settling time of h e tracking control at different operation speeds. In our experimental setup the settling time is in the range of 0.50 N 0.65 s for the conveyor belt running between 9.43 N 26.60 c d s . As we have seen, this is a great improvement in the tracking control compared with that where no special care is taken to compensate for the feedback ...

The paper presents a new voltage-mode universal filter using a differential voltage current conveyor transconductance amplifier (DVCCTA). It has three inputs and single output. The proposed circuit can simultaneously realize low-pass, band-pass, and high pass, band reject and all pass filter functions without changing the circuit topology and passive elements. The circuit exhibits a good freque...

A recent publication [l] introduced the concept of current conveying and an implementation in the form of a circuit building block termed the current conveyor (CC). This block has proven to be useful in many inst.rumentation applications, some of which have already been test)ed and reported [2], [3], while others are still under investigation. This correspondence introduces another new building...

This paper discusses the design of a hierarchically structured process planning system for a printed circuit board assembly hne. BasIcally. the assembly system consists of a series of mdependently operatmg placement modules, connected by a carrlerless conveyor system. Both the modules and the conveyor system are fully automated, while the complete system 1s also under centrahzed computer contro...

The tradition of implementing analogue circuits by means of voltage amplifiers is almost as old as the concept of electronic circuit design. The integrated electronic circuit, however, is a relatively new concept. Furthermore, integrated electronic circuits have significantly different limitations and strengths to the conventional discrete electronic circuits have. Since the active devices in i...
