In this paper, we compare different existing keeper techniques for reducing power consumption of wide domino logic circuits. We will compare power consumption plus area overhead of each of these methods, with the conventional keeper circuit. A 16-bit multiplexer circuit, in 0.13 mum CMOS technology operating at a frequency of 500 MHz is our test-bench. Simulations show split-domino (SD), with 53%...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
An on-chip buck converter with 3D chip stacking is proposed and the operation is experimentally verified. The manufactured converter achieves a maximum power efficiency of 62% for an output current of 70mA with a switching frequency of 200MHz and a 2x2mm on-chip LC output filter in 0.35mum CMOS. The use of glass epoxy interposer to increase the maximum power efficiency up to 71.3%, and the power efficiency...
This paper discusses the design of a 60 GHz low noise amplifier (LNA) using a standard low power SOI CMOS process from ST Microelectronics. First, we outline the technology as well as the mm-wave design challenges. Using recent work on coplanar waveguide (CPW) modeling, we describe how it's possible to use parametric, 3D electromagnetic simulation to complete or replace analytical models of on-chip...
This paper describes a comparative analysis between two topologies of operational amplifiers to design a 40 MS/s 12-bit pipeline analog to digital converter (ADC). The analysis includes AC and transient simulation to select the proper topology. This ADC is implemented in a 0.35 mum AMS CMOS technology with 3.3 V single power supply. The capacitors and selected operational amplifiers were scaled for...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...
The paper presents the design and implementation of input/output interface circuits, fully compatible with low-voltage differential signal (LVDS) standard. Due to the low voltage differential transmission technique, the low power consumption and high transmission speed are achieved at the same time. The transmitter is implemented by a closed-loop control circuit and an internal bandgap voltage reference,...
