Op-Amp Voltage Buffer
A voltage buffer, also known as a voltage follower, or a unity gain amplifier, is an amplifier with a gain of 1. It’s one of the simplest possible op-amp circuits…
Selection of electronic products I have led development from concept to production.
A collection of electronic circuits that I have designed..
Active High Pass Filter
An Active High Pass Filter can be created by combining a passive RC filter network with an operational amplifier to produce a high pass filter with amplification.
State Variable Filter
The state variable filter is a type of multiple-feedback filter circuit that can produce all three filter responses, Low Pass, High Pass and Band Pass simultaneously from the same single…
Active Low Pass Filter
By combining a basic RC Low Pass Filter circuit with an operational amplifier we can create an Active Low Pass Filter circuit complete with amplification.
Passive High Pass Filter
A High Pass Filter is the exact opposite to the low pass filter circuit as the two components have been interchanged with the filters output signal now being taken from…
Passive Low Pass Filter
Passive filters are made up of passive components such as resistors, capacitors and inductors and have no amplifying elements (transistors, op-amps, etc) so have no signal gain, therefore their output…
