Tiny Tapeout’s Post

I just verified my twin tee oscillator in silicon! This design was fabbed on Tiny Tapeout 7, which we just received from Efabless Corporation https://lnkd.in/dMwxmHsT This design uses a 'twin tee' filter in the feedback loop of an opamp. It was simulated to oscillate at 4.93MHz but I measured 4.67MHz - about 5% slower. Pretty close! Thanks to Alan Wolke (W2AEW) for the inspiration, Sai for the opamp design and Pat Deegan, KSC for the opamp layout. It was cool being able to reuse the open source silicon IP that other people have made!
