On ACC and Threshold Circuits
نویسنده
چکیده
We prove that any language in ACC can be approximately computed by two-level circuits of size 2('Ogn)', with a symmetric-function gate at the top and only AND gates on the first level. This implies that any language in ACC can be recognized by depth-3 threshold circuits of size 2('"gn)'. This result gives the first nontrivial upper bound on the computing power of ACC circuits.

Switched-Capacitor Dynamic Threshold PMOS (SC-DTPMOS) Transistor for High Speed Sub-threshold Applications
This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...

Let SYM + denote the class of Boolean functions computable by depth-two size-n log O(1) n circuits with a symmetric-function gate at the root and AND gates of fan-in log O(1) n at the next level, or equivalently, the class of Boolean functions f such that f(x1; : : : ; xn) can be expressed as f(x1; : : : ; xn) = hn(pn(x1; : : : ; xn)) for some polynomial pn over Z of degree log O(1) n and norm ...

A fundamental purpose of theory of computation is to understand differences between uniform computation and nonuniform one. In particular, Boolean circuit has been studied in an area of nonuniform computation models, because Boolean circuits are natural formalization of computer architecture and hardware. Boolean circuit is compared with uniform computation expressed as fixed size programs whic...

Due to the high density and the low consumption power in the digital integrated circuits, mostly technology of CMOS is used. During the past times, the Metal oxide silicon field effect transistors (MOSFET) had been used for the design and implementation of the digital integrated circuits because they are compact and also they have the less consumption power and delay to the other transistors. B...
