Abstract—An all-digital RF signal generator using /1/6 modu-
lation and targeted at transmitters for mobile communication ter-
minals has been implemented in 90 nm CMOS. Techniques such as
redundant logic and non-exact quantization allow operation at up
to 4 GHz sample rate, providing a 50 MHz bandwidth at a 1 GHz
center frequency. The peak output power into a 100
/10diff. load
is 3.1 dBm with 53.6 dB SNDR. B
