提出了一种基于上述互补金属氧化物半导体(CMOS)电感的射频片上系统(SoC)原型设计方法。在这种方法中，螺旋电感是在按常规制造工艺制造和切片的CMOS芯片上形成的。由于以上-CMOS电感的制造是以逐芯片的方式进行的，工艺简单，因此可以在很短的周转时间内进行电感的灵活调节和芯片性能的评估。因此，可以实现混合信号SoC的快速成型。这种技术可以理解为“芯片上的面包板”的实现，因为它是基于先试后试的实验方法。我们已经成功地在相同设计的不同芯片上制作了不同电感的CMOS超电感。文中还介绍了压控振荡器振荡频率的调节和低噪声放大器的阻抗匹配。
A new prototyping method for a radio frequency system on a chip (SoC) using above-complementary metal–oxide–semiconductor (CMOS) inductors is proposed. In this method, a spiral inductor is formed on a CMOS chip fabricated and diced by normal manufacturing processes. Since the fabrication of above-CMOS inductors is carried out in a chip-by-chip manner with simple processes, the flexible adjustment of inductance and the evaluation of chip performance can be carried out within a short turnaround time. Therefore, the rapid prototyping of mixed-signal SoCs can be realized. This technique can be understood as a realization of a “breadboard on a chip” since it is based on the experimental method on a cut-and-try basis. We have successfully fabricated above-CMOS inductors with different inductances on different CMOS chips of the same design. The adjustment of the oscillation frequency of a voltage-controlled oscillator and the impedance matching of a low-noise amplifier have also been demonstrated.
