Title: Injection locked oscillator: injection method
Post by mixed_signal on Feb 18^th, 2013, 1:23pm

Hi,
Which method of injection is low power consuming in injection locked oscillator?

1. Direct injection where MOS is connected in parallel to the tank

2. Indirect injection where MOS is connected like a diff pair

I think a lot more details about the optimization question are needed. For example, the frequency, technology of the oscillator (LC/ring - sounds as if it is an LC?), the motivation for the injection, and perhaps the application. It is difficult, for me anyway, to gauge what might be a reasonable answer from your basic question - sorry!
