This paper presents a 1.5-V CMOS true-single-phase (TSP) bootstrapped dynam
ic-logic (BDL) circuit using all-N-logic and bootstrapped circuit technique
s for high-speed operation at a low supply voltage. As confirmed by the exp
erimental results from the test chip implemented using a 0.8-mu m CMOS tech
nology, the speed performance of this CMOS all-N-logic TSP BDL circuit with
four serial inputs is 75% faster at a supply voltage of 1.5 V, as compared
to the conventional TSP dynamic-logic circuit. Using an all-N-logic TSP BD
L circuit, the maximum operating frequency of an implemented digital quadra
ture modulator is 482 MHz at 5 V, and 68 MHz at 1.5 V, which is 27% faster
compared to the circuit without using the BDL circuit.
