Voltage-to-Current Converter or Current
Source provided more High-quality Signals Transmission in Long Lines instead of
Tension Transmission. (Pic.1& Pic.2) Output Current Iout is determined by a
formulas:
- Amplification Factor of
Transistors.
Pic.1
Pic.2
Pic.3
Circuit (Pic.1& Pic.2)
Iout does not rely of Operational
Amplifier Tension. But Iout influences on Output Tension
Uin. This
failing is liquidated in Circuit Pic.3. If Transistors on one crystal are
used, where 
,
Error is 0.01%. Output
Current is determined by formula:
Pic.4 & Pic.5 Double-polarity Current Sources. Circuit Pic.4. Output Current is equal ± 10 мА. Output Signal is ± 10 V. Output Current Iout is determined by formula:
Non-linearity is ± 0.1%.
Pic.4
Pic.5
Pic.5. Not Ground Power Supply with General Unit. Displacement of zero is compensated on a resistor Ro.
