CMOS Inverter 125kHz LC Oscillator - This circuit uses a single CMOS inverter to
form a series resonant LD oscillator. The values shown set the oscillation
at about 125KHz but other frequencies are possible by changing the main LC values
….(designed by David A. Johnson) |
|
CMOS Inverters Form 125kHz Oscillator - This circuit is similar to schematic CMOS
INVERTER 125KHz LC OSCILLATOR but inverts the LC components so the inductor is
grounded. Two inverters are needed to produce the needed oscillation.
Again, the values shown set the frequency at 125KHz but can be changed to produce
other frequencies. ….(designed by David A. Johnson) |
|
CMOS Nand Gate Forms Gated 125kHz Oscillator - This circuit is similar to
schematic number 116 but uses a NAND gate as an inverter. The gate allows the
oscillator to be gated on and off. Again, the values shown set the frequency at
125KHz but can be changed to produce other frequencies. ….(designed by David A.

Low Power RFID Transponder - For some time railroad companies have been wrestling
with the problem of tracking rail cars. This has traditionally required manual log
entry of identification numbers displayed on the cars as they pass through the
switching yard….(diagram added 7/03) |
