This circuit generates quadrature signals, that is, with a 90-degree phase difference. The circuit must be powered by a symmetrical source and the frequency depends on the capacitors.
Figure bellow shows how the flip-flops of a 4027 can be connected to perform a divide-by-5 counter [odd...
The basis of this 90s circuit is a CA3130 operational amplifier. The circuit does not need a...
