RC and LC Lock Oscillator

 

Clock oscillators are circuits which generate square wave or nearlysquare wave signals suitable for digital electronics circuit asclock signal. The most common simple clock oscillator typesare resistor-capacitor (RC) and inductor-capacitor (LC) oscillators.

• CMOS Oscillator - 4 MHz oscillator using 74HC14 and inductor    
• CMOS inverter VCO tunes octave to UHF - robust and versatile vco provides a stable output to 300 MHz    
• CMOS RC circuits - includes CMOS 555 timer clock oscillator and schmitt-trigger RC oscillator    
• Crystal 32.768KHz CMOS Oscillator    
• Design and construction of radio frequency oscillators - Some people regard the design of RF Oscillators to be something akin to a "black art".    
• Sqaure Wave Oscillator - two gates from a CMOS 4011 NAND chip form a simpel square wave oscillator where the mark space ratio can also be independantly controlled by varying the value of the resistors
