Abstract:
A nonlinear oscillator comprising:a) a first linear amplifier, capable of receiving an input voltage (Vin) and outputting a first output current (I1); b) a second linear amplifier, operatively coupled to said first linear amplifier, wherein said second linear amplifier is capable of receiving said first output current and outputting a second output current (I2); and c) a nonlinear amplifier, operatively coupled to said first linear amplifier and said second linear amplifier, wherein said nonlinear amplifier is capable of receiving said second output current and outputting a third output current (I3); wherein said nonlinear oscillator outputs a first oscillator voltage (V1) and a second oscillator voltage (V2), and wherein said first linear amplifier, said second linear amplifier and said nonlinear amplifier have a substantially similar design that includes an adjustable linear transconductance region width, and wherein input/output characteristics of said nonlinear oscillator maintain the following relationship: {umlaut over (x)}=2&mgr;(1âˆ’&eegr;x2){dot over (x)}âˆ’&ohgr;2x.
