rfid tank circuit

An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together. The circuit can act as an electrical resonator, an electrical analogue of a tuning fork, storing energy

本文探讨了在高频条件下，传统电阻负载在共源放大器中增益下降的问题，并提出使用并联LCtank作为负载以提高增益性能的方法。 通过分析LCtank的不同配置及其对品质因数Q的影响，展示了如何实现宽带放大器电路。 可以看到，对于阻值比较大的电阻来说，频率越高，电阻值越低。 因此CS电路的增益会随之下降，无法实现较好的放大器增益特性。 这个时候我们可以用并联LC tank来代替阻性负载，如下图的放大器电路所示。 因为谐振时并联LC tank可以视为无穷大的电阻，与漏极电流相乘可以得到幅度更大的输出，因此可以实现更好的增益性能。 通过多个LC tank之间的相互配合，可以实现宽带的放大器电路。
