Amplifiers
Hello. Can anybody help me with a problem that im having. I have designed a system that has a very low signal to noise ratio. The signal that i am trying to measure is changing very slightly and it is hard to measure due to all the noise that i am getting. The noise is completly random but is...- LezBurns

Oscillator circuits
Can anybody help ive have done some calculations and my capacitance change is going to be in the range of 0.5pf to about 3pf where do i go about getting a wien Bridge oscillator that is affected by this amount of change quite drastically so the frequency ouput changes accoridingly.- LezBurns

Oscillator circuits
Firstly i would like to thank you all for your replies, they are much appreciated. Ok I need the frequency to be altered as much as possible really with only very small adjustments in capacitance. My aim is to produce a capacitance based micro-sensor that can monitor the movements of a human...- LezBurns

Oscillator circuits
Hello. Can anyone help me I have a bit of a proble. My electronics skills are quite limited but I have a grasp of the basics. I want to create a high frequency oscillator circuit in the range of around 10MHz. But I also need to be able to affect the frequency of the oscillator using an...- LezBurns
