aniruddha Posted April 10, 2007 Report Share Posted April 10, 2007 Hi,Please could anyone provide a ckt. diagram for a 40 Khz sinusoidal oscillator.A circuit using a IC will also do. ORA circuit using discrete components like transistors etc will also do.In short any 40Khz sinusoidal oscillator design is welcome.Please provide any or as many designs as possible ... all are most welcome.The frequency must be stable.

aniruddha Posted April 10, 2007 Author Report Share Posted April 10, 2007 Also if possible also suggest a scheme for the amplitude of the sinusoid to be around 22 to 28 Volt peak-to-peak.Thanks in advance. Quote Link to comment Share on other sites More sharing options...
AN920 Posted April 10, 2007 Report Share Posted April 10, 2007 Do you want to use it for ultrasonic transducer? Transducer will work with square wave as well. Quote Link to comment Share on other sites More sharing options...
saveas_gg Posted April 11, 2007 Report Share Posted April 11, 2007 u could use IC timer for creating 40kHz of frequency...using Ra and Rb to found the T(low) and T (high)..f=1/(T(low) +T (high))=40kHz approximately..... Quote Link to comment Share on other sites More sharing options...
