摘要：
A driver circuit for supplying a drive signal to a mixer circuit comprising a first and second circuit branch and an operational amplifier. The first circuit branch receives an input signal and a bias signal. The second circuit branch receives the input signal. The operational amplifier has a first input connected to a junction node of the first circuit branch and a second input connected to a junction node of the second circuit branch. The operational amplifier is arranged to provide an operational amplifier output signal a second component of the second circuit branch so that a voltage at the junction node of the second circuit branch is equal to a voltage at the junction node of the first circuit branch. The voltage is dependent on the input signal and providing the drive signal.
