Signal Generator circuit
The output level was set to 3.8V peak to peak. The initial objective was to compare several different operational amplifiers (op-amps) before further optimizing the circuit. The op-amps evaluated were the TL072, LM4562, and OPA2134. The distortion spectra are presented...
High-performance quadrature sine wave type oscillator circuit
Many RC oscillators utilize advanced circuits within the phase shift unit. These circuits employ voltage feedback amplifiers, whose gain decreases significantly at high frequencies and ceases when high frequency is not attained. The variation in the phase characteristics of the...
Easily Tuned Sine Wave Oscillators
One approach to generating sine waves is to filter a square wave. This leaves only the sine wave fundamental as the output. If a lower distortion oscillator is needed, the circuit in Figure 2 can be used. Instead of driving...
12vdc to 220vac inverter with sine wave output
In DA3, DA5, VT1, and VT2, the first channel of the VLF Class D amplifier is assembled. The second channel is constructed using DA4, DA7, VT3, and VT4. Antiphase sine waves in the VLF range are formed at the outputs...
