My company is switching to Altium Designer from OrCAD. I am setting up the new schematic page templates.
Our schematic drawings are all D-size and are often printed on 11" x 17" paper, which is half scale. Per ANSI/IEEE Std 991, line spacing that has lettering between (i.e. signal names) must...
The simplest way to create a DOS system disk is to boot into DOS using the floppy or USB drive and then format the hard drive using the "/S" option to copy the system files to the disk. Based on how old DOS is, this may or may not support gigabyte class hard drives. Or a large drive may appear...
There are two ways to set up your FPGA architecture using an embedded Microblaze processor. 1) You can have the Microblaze be the top level of your design and add your custom VHDL code as a Microblaze peripheral. 2) You can have your custom VHDL logic be the FPGA top level design and...
O ohm Resistor
Another good use for zero ohm resistors is to be able to isolate part of the circuit for debug purposes. For example, if you need to debug a switching power supply, a zero ohm resistor on the output may be removed to isolate the rest of the board while an external load is attached.
cmos pull up resistor
This discussion assumes 5 V Vcc.
TTL output levels must only drive 2.0 volts or greater for a logic high level. In addition, many TTL drivers source less current than they sink, meaning that while they may be rated for 4 mA drive for logic high, they might be rated at 12...
