Abstract
An oscillator includes a first node having a first bias voltage, a second node having a second bias voltage, and a reference node having a reference voltage. A forward stage includes a first terminal coupled to an output terminal of the oscillator, and a second terminal coupled to one of the first node, the second node, or the reference node. A transformer-coupled band-pass filter (BPF) is coupled between the output terminal and a third terminal of the forward stage.
