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。
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。
Could anybody explain it? thank you。
