dvances in IC fabrication technology , coupled with aggressive circuit design, have led to exponential growth of IC speed and integration levels. For these improvements to benefit overall system performance, the communication bandwidth between systems and ICs must scale accordingly. Currently, communication links in various applications approach Gbps data rates. These applications include compu...

For the purpose of realizing a new intelligent system and its simplified VLSI implementation, we propose a new nonvolatile analog memory called “switched diffusion analog memory with feedback circuit (FBSDAM).” FBSDAM has linear writing and erasing characteristics. Therefore, FBSDAM is useful for memorizing an analog value exactly. We also propose a new analog content-addressable memory (CAM) w...

In this paper, a new circuit scheme is proposed to reduce the power consumption of dynamic circuits. In the proposed circuit, an NMOS keeper transistor is used to maintain the voltage level in the output node against charge sharing, leakage current and noise sources. Using the proposed keeper scheme, the voltage swing on the dynamic node is lowered to reduce the power consumption of wide fan-in...

A novel current controlled CMOS ring oscillator is presented in this paper. Specially circuit structure and transistor parameters design is used to obtain good temperature coefficient.

The test result shows that th...

A new CMOS buffer without short-circuit power consumption is proposed. In this work, the gate-driving signal of the output pull-up (pull-down) transistor is fed back to the output pull-down (pull-up) transistor to get tri-state output momentarily, eliminating the short-circuit power consumption. The TSPICE simulations are used to verify the operation of the buffer. It is observed that the power...

This paper presents the design of low power and high speed circuit using a new CMOS logic family called feedthrough logic. FTL arithmetic circuits provides for smaller propagation time delay when compared with the standard CMOS technologies. The proposed circuit has very low dynamic power consumption and lower propagation delay compared to the recently proposed circuit techniques for the dynami...

Historically, dynamic CMOS was used sparsely by using the property of dynamic nodes. If the transistor leakage current is relatively low so that a circuit node can retain its charge for a relatively long time, the presence and absence of charge can be used to interpret particular information. This is similar to the principle used in dynamic memories and it brings the same benefits of simpler an...

Capacitor-couple technique used to lower snapbacktrigger voltage and to ensure uniform ESD current distribution in deep-submicron CMOS on-chip ESD protection circuit is proposed. The coupling capacitor is realized by a poly layer right under the wire-bonding metal pad without increasing extra layout area to the pad. A timing-original design model has been derived to calculate the capacitor-coup...
