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.

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.
