PWM Tutorial 2 – Using PWM and an H-Bridge to Control Motor Speed

This tutorial continues from where PWM Tutorial 1 left off

Introduction

The purpose of this tutorial is to apply the “breathing” PWM approach toward a motor driven by an H-Bridge

PWM Tutorial 3 – Using Low-Pass Filters with PWM Signals

This tutorial continues from where PWM Tutorial 2 left off

Introduction

The purpose of this tutorial is to walk you through the steps of using a low-pass filter with a PWM output in order to generate an analog signal.

Report Formatting Instructions

Introduction

Formatting is important.  It makes documents more legible and helps direct the reader to more easily find the information they want, through consistency of styling and predictable flow.

Resetting Reference Designators in Cadence Design Entry CIS

Introduction

When drawing a circuit, you will often move and delete components as part of the process, meaning that the reference designators (e.g., R1, C1, U1) may be out of order or scattered throughout your design. This tutorial walks through how to reset the reference designators so they are sequential.

Rubout Area for your PCB in KiCad

Background

What is a Rubout area?

Some electrical components will contain an antenna for wireless communication. These antennas can be affected by electromagnetic interference that are near the antenna. A “Rubout area” (also known as a “Keepout area”) prevents traces and components from being placed in a specific location. These can protect the antenna from any interference.

Running a Design for Manufacturing Check in DFM Now

This process has been replaced with a superior web-based Peralta Studios DFM Checker.

Introduction

Designs created in an ECAD program may be electrically correct on the screen, but are ultimately constrained by the capabilities of your fabrication equipment. This tutorial walks through how to use the program DFM Now to verify that a design is able to be manufactured by the LPKF ProtoMat S63 in PRLTA 109.

Running Design Rules Check in Cadence PCB Editor

What is a Design Rules Check?

Design Rules Check (DRC) is a tool that looks for a limited set of errors in PCB designs, and generates error messages to help you identify and fix the problem(s). A design that passes a DRC is not necessarily error-free, but rather has passed the limited set of tests that DRC conducts. You can (and should) run a DRC in both Design Entry CIS and PCB Editor, and they will look for different types of errors.
