项目概况
比翼双飞是什么意思摘要：A constant-current source including a constant-current output circuit for
supplying a constant current provided with one or more transistors with the bas biad with the same ba potential, a first circuit which provides a first current signal for tting the strength of the constant current to be delivered from the constant-current output
circuit, a cond circuit which generates a cond current signal and provides the same ba potential in respon to the cond current signal, a third circuit which controls the cond current signal to minimize any deviation of the cond current signal from the first current signal, and a DC power supply for energizing at least the first, cond and third circuits. The improvement is that the transconductance of the first circuit which reprents the ratio of a change in the first current signal to a change in the output voltage of the DC power supply is equal to the transconductance of the cond circuit which reprents the ratio of a change in the cond current signal to a change in the output voltage of the DC power supply.
