A patent-pending wafer process, that’s an alternative to MOS and bipolar technology.
Bizen, an acronym of bipolar and Zener, uses Zener quantum tunnel mechanics to provide a different way to isolate the base well called the ‘Tunnel’ terminal. Designers can do away with the resistor, like in MOS and take advantage of the now controllable current. With Bizen, the output terminals that would normally be called the emitter, source, collector or drain, are instead called Anode 1 and 2. The two regions are identical, meaning the transistor has identical forward and reverse characteristics, allowing for AC signals and push/pull circuits.
The result is a disruptive wafer process with lower dynamic power, higher speed and higher gate density, all slingshot by 1\2 the process layers, 1\3 the material use and 1\10 the lead time.
Is there any experimental data which supports the claim of HV support, please? I would be very interested to know. Thank you

We are considering early adopter in-house projects to verify the PDK. Please get in touch if you wish to be considered.
In Bizen, you will be able to combine both the digital part of your circuit and power. 40V, 1A is no issue given 1200V 200A is our release target.
It’s not apparent but yes Bizen can be comparable to a push-pull technology such as complementary NPN PNP with the ability to push and pull current. Fast diodes, Schottky diodes, capacitors will also be in the PDK although we believe once you understand the PDK, you would switch to quantum tunnel parts.
Pseudo memory types are possible, but not available yet.
A Cadence PDK will be made available but due to the complexity of spice, only in Cadence and not yet.
