Abstract
This paper proposes a new power and area efficient circuit configurations, and also an optimization design method for such configurations. Two types of loopfilters are fabricated, one is a third-order integrator with single opamp for mobile TV-tuners (Modulator A) and the other is a fourth-order (Modulator B) for wide-band mobile receivers. Modulator A and Modulator B are fabricated in 65 nm and 40 nm CMOS processes, respectively. Results show that the new filter with an efficient optimization tool is a very powerful way to develop high efficient ΔΣ.
