    Hi, I need to emulate a crystal oscillator circuit (attached) based on wave digital filter (WDF). Basically we aim to have WDF emulation that match a Spice simulation (e.g. in Cadence). I Already have the circuit simulated in Cadence (the output attached) . Attached, my circuit (Crystal Oscillator) schematic that needs to be mapped to WDF along with its output waveform, you will notice that there ...
