The present disclosure relates generally to systems and methods for tuning
power consumption and group delay in circuits such as radio frequency
integrated circuits (RFICs). In one example, a system includes first and
second gating blocks configured to reduce a first clock signal operating
at a first clock rate to a second clock rate and a third clock rate,
respectively. A first processing block coupled to the first gating block
operates at the second clock rate. A second processing block is coupled
to the first processing block and the second gating block, and operates
at the third clock rate. The first processing block changes a flag state
from a first state to a second state when transmitting a first data
sample to the second processing block, and changes the flag state from
the second state to the first state when transmitting a second data
sample to the second processing block.
