- Abstract
- A 12 GHz PLL with digital output phase control
has been implemented in a 90 nm CMOS process. It is intended
for LO signal generation in integrated phased array transceivers.
Locally placed PLLs eliminate the need of long high frequency
LO routing to each transceiver in a phased array circuit.
Routing losses are thereby reduced and design of integrated
phased array transceivers become more modular. A chip was
manufactured, featuring two separate fully integrated PLLs
operating at 12 GHz, with a common 1.5 GHz reference. The chip,
including pads, measures 1050x700 μm2. Each PLL consumes
15 mA from a 1.2 V supply, with a typical measured phase... (More) - A 12 GHz PLL with digital output phase control
