This circuit of the 70's uses transistors of the time. The circuit can amplify signals from 10 Hz to 100 kHz and modern equivalent components can be used. The circuit is from Ferranti.
This circuit uses common CMOS components. We found it in the July 1987 issue of Radio Electronics...
The circuit presented was found in a Texas Instruments optoelectronics manual. The signal must be...
Other series amplifiers such as the MC3301, MC3401 and LM2900 can be used on this circuit. We...
