Circuits Designed by Dave Johnson, P.E. :

Links to electronic circuits, electronic schematics, designs for engineers, hobbyists, students & inventors:
I.F. Amplifier - The I.F. transformer primary has 18 turns, the secondary winding has 4 turns. The capacitors across the IFT primaries are 82pF. The input/output transformer has 12 turns, tapped at 3 turns from ground. This transformer is wound on a ferrite core. The mosfets are 3SK45's. The diodes in the product detector are 1N34's. I use a six pole SSB filter from a scrap CB. The centre frequency is 7.8MHz. The -6db bandwidth is about 2.5KHz. (added 2/05)
IC Forms Differential Line Driver/Receiver - 05/25/95 EDN-Design Ideas / (added 3/03) you can use the HFA1212 dual video buffer to implement differential line drivers and receivers with a minimum of external components
Improved Infrared Receiver with status led - This is a general purpose serial port infrared receiver. With the help of appropriate software (see below) you can control different functions of your pc from a distance. For example you can control your home cinema settings (volume, play, pause, stop etc), your winamp etc....(circuit added 09/08)
Induction Receiver - The induction receiver shown below is very sensitive and can serve a variety of purposes. It is excellent for tracing wiring behind walls, receiving audio from an induction transmitter, hearing lightning and other electric discharges, and...(diagram added 8/03)
Infrared Receiver for Sony Remotes - receive signals from a standard Sony remote control and send the code bytes(2) received to an RS-232 port, based on PIC16C84 (added 4/02)

Miniature FM Radio Receiver using TDA7088 - The electronic diagram of the monophonic FM receiver made with TDA7088T is shown on Pic.4.12. If built with SMD components it can be placed in a matchbox, altogether with two button-type batteries. The operating principle of this device is given in the previous t....   (added 11/05)
MK484 AM Receiver - A complete AM radio set based on the MK484 IC (formerly ZN414). It uses a PNP transistor and can drive a 150R loudspeaker.   (added 11/05)
MPF102 FM Receiver - (electronic schematic / circuit added 4/02)
MPF102 Receiver - (design added 8/03)
MRX 40 Mini Receiver - (design added 8/03)
Nostalgic Crystal Radio - ….(design added 08/08)
One Transistor Regenerative Receiver - (design added 8/03)
One-Transistor Amplifier/Detector - An amplifier may be added to boost the audio level as shown below. The current consumption of this amplifier is quite low and a power switch is not included. Disconnect the battery when the receiver is stored for long periods….(added 04/05/06)
One-transistor Regenerative AM Receiver - A classic design revamped slightly. Features a single-transistor regen stage, and a range of 1000 miles with a 4-foot antenna. Perhaps the best "survival radio",….(circuit design added 06/06)
