Abstract :
The design of oscillators using linear 2-port networks are well documented and are usually based on circuits using one active device. Recently there has been renewed interest in the cascode circuit because of its injection locking properties. This gives it tremendous possibilities, in providing very stable high frequency oscillators by locking it to a more stable lower frequency source. The design of oscillators using the cascode circuit has never been completely approached analytically before so the purpose of this paper is to present a method that will enable the analytic approach to oscillator design using the cascode circuit. This method is verified with a design of a low cost, low phase noise power oscillator at 850 MHz
