標題: Voltage-to-Current Converter [打印本頁] 作者: wwm101 時間: 2009-6-25 04:22 PM 標題: Voltage-to-Current Converter In the paper 'A Wideband CMOS Variable Gain Amplifier With an Exponential Gain Control'，a Voltage-to-Current Converter is realized and the structure is shown in the following figure。 # L( A' B! S- A* C6 G3 W! q% ~ [attach]7276[/attach]8 g4 O' r/ \2 \
In the figure，VC** denotes the voltage copier and current generation，Here ，i don't understand why VC** can copy voltage from node A to node B。4 n& f! _9 o/ H; _0 E4 }1 o- }
5 U. y% w! f( J" r+ x/ n
Could anybody explain it？ thank you。
