Constant biasing circuit and operational amplifier using said circuit |
摘要 |
A constant biasing circuit is made to maintain a fixed difference of potential between two circuit nodes A and B otherwise at floating potential levels. The biasing circuit is made of series connected complementary transistors disposed between the circuit nodes A and B and having their gate electrodes respectively connected to opposite voltages of, e.g., +5 volts and -5 volts.
