About Minimal Fab and the ICPS PDK

Introduction

Recently I participated in the Minimal Fab Design Contest. I had a go at designing a transmission-gate D-FF using the provided template for the layout. You could only use the first metal layer to connect devices.

It was actually selected for fabrication! This image shows the layout of the wafer with all the submitted designs:

My design is the second die in the first row of the 5x5 array.

This was only possible because the Industrial CPS Research Center (ICPS) at AIST (Advanced Industrial Science and Technology) in Japan open sourced their PDK for the Minimal Fab SOI-CMOS process. In a follow-up blog...

Ламповый дисплей для компьютера. Часть 2 – ускорение и фокусировка электронов в ЭЛТ

В предыдущей части я привел обзор ряда подходов к созданию необычного дисплейного устройства. В отличие от приведенных примеров мне хотелось создать дисплей, который будет пригоден для регулярного пользования. Для этого я выбрал круглую индикаторную ЭЛТ от радиолокационной установки с зелёным цветом свечения экрана. О том, как удалось заставить её работать, рассказывается в этой статье.

Cutting Pins for F Nixie tube | EP#3

https://invidious.privacyredirect.com/watch?v=9Gsk4Y-N4iA

Another version of a mold for manufacturing stems is in development. Meanwhile, I am trying the process of cutting wires to pins – this will be needed once the mold is ready..

Ламповый дисплей для компьютера. Часть 1 — обзор концепций и постановка задачи

Всем привет! Мне с большим трудом удалось побороть лень и начать писать новый цикл статей, но на этот раз не о лазерах. Дело в том, что лазеры – не единственный мой интерес, значительное место в списке интересов у меня занимает ламповая техника в её разнообразных проявлениях, и совершенно особый фетиш – советская ламповая радиолокационная аппаратура. Мне давно хотелось отвлечься от лазеров и создать что-то такое, что, как бы это ни звучало банально, не имеет аналогов. Потому вспомнил одну старую идею, очень долго лежавшую в «долгом ящике». И речь в статье пойдет о нестандартных устройствах отображения визуальной информации.

App note: The difference between current sense resistors and hall effect sensors for motor control

App note from Bourns’ comparing current shunt resistors and hall effect current sensing pros and cons. Link here (PDF)

Current sensing is an essential design function that is necessary in a broad range of applications. For example, current sensing is needed to detect a battery’s capacity, to measure current flow, or to calculate angles in motor control applications. Applications that can benefit from current sensing include Battery Management Systems (BMS), 3-Phase motor control units and On-Board Charging (OBC) Systems used in electric vehicles (EVs), and in other high energy charging-based designs.
Current sensing is also advantageous in medical equipment to detect leakage...
