our engineers have completed over 20 custom chip designs during their careers including ones for very high volume consumer electronics projects.
Battery-operated low-power consumer electronics aren't really relevant to mining hardware which is high-power application that pushes itself to the edge of death: either thermal from overclocking or starvation from undervolting.
Were also making extensive use of analogue design techniques to minimise noise and reduce supply voltage again saving power. Every transistor we save, shrink or optimise saves power, and overall this results in greater power efficiency.
Good. Analog and mixed-signal design flow is the way to go. Now please get back with your engineers and post some results of your preliminary simulations. E.g. which version of BSIM did you use? You could post some fragmentary results without disclosing the entire design.
This board has enough people that will understand such posts. And disclosing some technical data (even incomplete) will be the quickest way to distinguish you from all the previous scammers who only had marketroids at the ready and literally nobody to back them up on the technical front.
