The analog T-switch (AT-switch) scheme is introduced to suppress subthreshold-leakage problems in charge-based analog circuits such as switched capacitors and sample-and-hold circuits. A 0.5-V sigma-delta modulator is manufactured in a 0.15-/spl mu/m FD-SOI process with low V/sub TH/ of 0.1 V using the concept. The scheme is compared with another leakage-suppression scheme based on super cut-off CMOS (SCCMOS) and the conventional circuit which are also fabricated. The sigma-delta modulator… CONTINUE READING
