(English Abstract) |
A low phase noise, multi-standard local oscillator (LO) chain for LTE and GSM is presented. The LO chain is composed of a dynamic divider and a CMOS VCO with a hybrid inductor using both bondwire and a planar spiral inductor in the same area. This approach improves both tuning range and phase noise characteristics without additional area loss. Based on this concept, the LO chain with a hybrid inductor VCO is implemented in a 65nm CMOS process. The measured performance satisfies wide tunability and most stringent GSM transmitter phase noise specification, which proves that the LO chain can be used for LTE and SAW-less GSM transceiver. |
