FPGA Implements X50 Division 3 Recommendation - 04/13/00 EDN-Design Ideas
The scheme in Figure 1a uses five delay cells and an XOR gate to configure the data
stream for the X.50 Division 3 recommendation of ITU-T. The X.50 recommendation
defines the fundamental parameters of a multiplexing scheme for interworking data
networks using different envelope structures. Division 3 applies to the interworking
between two networks, both of which use the 8-bit envelope structure....[Design Idea

Get just enough boost voltage - 27-May-04 Issue of EDN Adding a
current-mirror circuit to a typical boost circuit allows you to select the amount of
boost voltage and to ensure a constant difference between the input and the output
voltages (Figure 1]. This circuit is useful for high-side-drive applications, in
which a simple voltage doubler is unacceptable because of the voltage range of the
components involved or where the input voltage can vary.... [Design Idea by Kieran

Gold Wafer Smartcard Programmer - This circuit is a combination of a
ludipipo programmer (for pic) + phoenix programmer (for the eeprom 24LC16). You
can't program pic and eeprom with ludipipo programmer. The big advantage of this
circuit is that use just one port from your computer (RS232) in reverse with other
programmers that use both RS232 and parallel. The disadvantage is that you must select
the component to be programmed with a switch and not electrically and that you can
only program 16F84....(electronic circuit added 4/05) |
