CS-3 Diode Connected Transistor : V D bipolar diode exponential diode connected transistor quadratic WebAn efficient way of doing this is to use a noise filtering technique. An inductor L3 and capacitor C5 forms a 2nd order low-pass filter which prevents noise at even harmonics from being injected into the feedback path of the oscillator. The noise filter leaves low-frequency noise from the tail current source unaffected.
