Mixed Signal Grounding Method
How do we interface Analog and Digital Blocks. The earlier post explains ground connections that are radiating from supply but does not show Analog and Digital Blocks Interface.

LM3914 Circuit Ground Connections
I am about to build the circuit that you have here: – Millivolt Meter – Bargraph I am pretty sure that I understand all of it, except for the symbols that you have at...
ICL7135 PCB Layout Method
I have design a PCB layout for a 4.5 digit voltmeter using the ICL7135 chip, and i have problems with the analog and digital ground. Do you know if somebody have make a PCB...
Mains Stability and Supply Regulation
I have problem with my power supply… . The power supply uses LM317 and TIP2955 and the unstable AC net here causes the output to drop sometimes below 5V. The normally output is 13,5V....
Spice Simulation for CD4060
I found your web site today. I am looking for the CD4060 spice model for Orcad Capture. My Orcad version is the 9.2 (complete but without CD4060 !!) I saw on your web pages...
Simple High speed data switch
This circuit is a small representation of a very low cost printer sharer. It has no Active Devices only diodes.
Battery Management and Supply Design
As you have have pointed out, my circuit is not driving any motor or such loads…but it is driving a Wireless Module which draws about 165mA to 240mA from my circuit during transmission [for...
RS Latch Erroneously setting by Itself
I am having trouble preventing my rs latch from erroneously setting. The circuit is a voltage threshold detection circuit with a nand gate whose output is tied to a SR latch.
