This paper presents the design of a novel low-voltage high-speed D-latch circuit suitable for nanometer CMOS technologies. The proposed topology is compared against the low-voltage triple-tail D-latch and its advantages are demonstrated both by simulations, under different performance/power consumption tradeoffs with a 40-nm CMOS technology, and theoretically, thanks to a simple model of the propagation...
In this paper, a novel circuit topology is presented for Clock gating cell in which the basic parts (gater and latch) are realized with transmission gate. The simple structure and small amount of leakage power make this topology suitable for ultra-low power designs in sub/near-threshold regions. Circuit simulations and Post-Synthesis simulation results of a simple Clock gated ITC'99 benchmark circuit...
This paper discusses a novel clock gating cell (CGC) optimized for high performance and low power design. The conventional CGC is analyzed along with other low power implementations of the CGC that have previously been proposed. The new CGC topology is proposed and compared to the topologies previously introduced in terms of dynamic clock power, leakage, area and timing.
This paper discusses a novel clock gating cell (CGC) optimized for low-power and low-voltage operation. First, the limitations of the conventional CGC topology are analyzed and several improvements are proposed. Next, the new CGC topology is introduced and compared to the conventional one in terms of dynamic clock power, leakage, area, timing, and low-voltage operation. Finally, the paper discusses...
This paper compares readout powers and operating frequencies among dual-port SRAMs: an 8T SRAM, 10T single-end SRAM, and 10T differential SRAM. The conventional 8T SRAM has the least transistor count, and is the most area efficient. However, the readout power becomes large and the cycle time increases due to peripheral circuits. The 10T single-end SRAM is our proposed SRAM, in which a dedicated inverter...
This paper describes a design flow for the circuit-level optimization of a technology. The concurrent exploration of device characteristics and library design choices leads to a more application-optimal technology. We illustrate the design flow by: 1) analyzing the impact of buffer cell design, and 2) by optimizing a 130 nm technology for low operational power.
3D contactless technology based on capacitive coupling represents a promising solution for high-speed and low power signaling in vertically integrated chips. AC coupled interconnects do not suffer from mechanical stress, and the parasitic load is much reduced when compared to standard DC solutions, such as wire bonding and micro bumps. Communication system based on wireless interconnection scheme...
