Abstract: Minimizations of power dissipation, chip area with higher circuit performance are the necessary and key parameters in deep submicron regime. The leakage current increases sharply in deep submicron regime and directly affected the power dissipation of the logic circuits. In deep submicron region the power dissipation as well as high performance is the crucial concern since increasing importance of portable systems. Number of leakage reduction techniques employed to reduce the leakage current in deep submicron region but they have some trade-off to control the leakage current. ONOFIC approach gives an excellent agreement between power dissipation and propagation delay for designing the efficient CMOS logic circuits. In this article ONOFIC approach is compared with LECTOR technique and output results show that ONOFIC approach significantly reduces the power dissipation and enhance the speed of the logic circuits. The lower power delay product is the big outcome of this approach and makes it an influential leakage reduction technique.
Abstract: In this paper, a new BiCMOS CCII and CCCII,
capable of operate at ±0.5V and having wide dynamic range with
achieved bandwidth of 480MHz and 430MHz respectively have been
proposed. The structures have been found to be insensitive to the
threshold voltage variations. The proposed circuits are suitable for
implementation using 0.25μm BiCMOS technology. Pspice
simulations confirm the performance of the proposed structures.
