Frequency tuning for lc circuits

摘要: Apparatus and methods are disclosed related to tuning a resonant frequency of an LC circuit. In some implementations, the circuit can be embodied in low noise amplifier (LNA) receiver. The receiver include component configured generate indicator received signal strength indication (RSSI) radio (RF) by A control block adjust based at least part on RSSI. As another example, oscillator, such as VCO, separate from that used tune These apparatus compensate for variation zero imaginary impedance across
