A PLL based 12GHz LO generator with digital phase control in 90nm CMOS

Axholt, Andreas LU and Sjöland, Henrik LU orcid (2009) Asia Pacific Microwave Conference, APMC 2009 p.289-292
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)
