Hello Engineer ,

Have you ever wondered what would really happen if you flipped the standard CMOS inverter layout—placing the PMOS at the bottom and the NMOS at the top?

It’s more than a theoretical puzzle. This configuration violates the fundamental biasing of the transistor substrates, instantly forward-biasing the source-body diodes and creating a low-impedance path from VDD to GND. The result isn't a logic error; it's a catastrophic, current-destroying short circuit that would fry your design.

This is just one example of how deep silicon-aware knowledge separates a functional schematic from a robust, manufacturable circuit.

If you want to move beyond theory and learn the rules of the silicon that make or break a design, you need hands-on experience with a real PDK.

That’s exactly what we offer in our upcoming workshop: CMOS Circuit Design & SPICE Simulation using Sky130 Technology.

In this intensive workshop, you will:

• Get hands-on with a Commercial-Grade PDK: Work with the open-source Sky130 process design kit, the same technology used in successful tape-outs.
• Master SPICE Simulation: Move beyond ideal models. Characterize real inverters, plot VTC curves, and analyze performance metrics like rise/fall time and propagation delay.
• Understand Latch-Up & Prevention: Learn firsthand the mechanisms behind latch-up (which the "upside-down inverter" would cause) and how to prevent it in your layouts.
• Design, Simulate, and Analyze: From schematic entry to post-layout simulation, you'll complete the full flow for fundamental CMOS circuits.

This is your chance to bridge the gap between academic concepts and industry practice.

Registration for this workshop closes in exactly 1 day.
Spots are limited to ensure a quality, hands-on experience for all participants.

Don't just design circuits. Design circuits that work.

P.S.: This workshop will give you the practical skills to avoid multi-million dollar mistakes. The cost of not understanding these principles is far greater than the cost of enrollment. Secure your spot before tomorrow's deadline.
