The sense resistor is sized to select the current supplied on a given slot voltage. The flat pack resistor portfolio covers the lower power range fr om 075 75 kw both t2 t4 and t5 and intended for horizo ntal applications conveyors.

        Resistor layout pdf. Rectangular snake resistance at the corners current flows in different directions dont use it in precise applications. The layout frequency response in high frequency region the parasitic resistance and the parasitic capacitance raise an unintended pole and zero. This tutorial shows layout of capacitor and resistor.
Resistor extract the layout using the extractor tool in cadence and and see the value in extracted view of your cell and change the size of the resistor in layout view to get to a desired value. Pattern styles for thin film flat chip resistor arrays limits for solder resistance occupied area x i p z 01 g y n dimensions in mm recommended solder pad dimensions for fixed linear thin film flat chip resistor arrays acac and application specific resistor arrays asra type g mm y mm x mm z mm i mm p mm acac 07 07 05 21 03 08. This would help us make the resistor layout almost equally spaced in length and width rather having a long layout.
Many types of resistors are used having different uses and construction. Resistor construction resistors are components used to resist the flow of electric current and have a stated value of resistance. Precision of the circuit operation common centroid layout of mosfet c and r can improve the.
On these products the pfbout pin should be tied to the pfbin1 2 pins using as much pcb copper as possible. See figure 10 figure 10. Because of the tolerance on the controllers comparator input voltage the circuit design and layout must consider the high end of the current range for etch runs and vias.
The long interconnect acts as a parasitic inductor or lc resonator. In order to have large value resistors. A circuit that is design for 12 a minimum often supplies current to a.
Use of long strips large lw use of layers with high sheet resistance bad performances layout. A 100 uf tantalum capacitor in parallel with a 01 uf cap should be placed close to the pfbout pin and 01 uf caps should be placed close to the pfbin1 and pfbin2 pins. Capacitor and resistor layout.
At this point you should have set up the environment and successfully completed the inverter tutorial or otherwise know how to do layout using virtuoso. Maloberti layout of analog cmos ic 22. If you have not set up your unix environment refer to setting up your unix environment.
With the compact flat pack resistor it is possible to mount th e resistor on the rear of a vlt fc series frequency converter. For example the following figure shows a 50k resistor in a serpentine pattern rather having a long resistor of length 120um.
