This paper introduces a high-speed high resolution CMOS current comparator which is used in an algorithmic Analog-to-Digital Converter (ADC) and implemented with a 0.6 μm standard CMOS process. Circuit occupies 170 x 80μm2. Proposed circuit performs comparison over a precision of 10bit at a 100MHz clock within the 0-250 μA input current range. Power consumption is less than 500 μA.
Fabrication of an integrated circuit with smaller area, besides reducing the cost of manufacturing, usually causes a reduction in the power dissipation and propagation delay. Using the static CMOS technology to fabricate a circuit that realizes a specific logic function and occupies a minimum space, it must be implemented with continuous diffusion runs. Therefore, at the design stage, an Euleri...

Systems-on-chips (SoCs) that combine digital and high-speed communication circuits present new opportunities for powersaving designs. This results from both the large number of system specifications that can be traded off to minimize overall power and the inherent low capacitance of densely integrated devices. As shown in this paper, aggressively scaled silicon-oninsulator (SOI) CMOS is a promi...
This paper describes analog/mixed-signal circuit design in the nano CMOS era. Digitally-assisted analog technology is becoming more important, and as an example, our fully digital FPGA implementation of a TDC with self-calibration is shown. Since pure analog circuits are still present and “good” device modeling is required for their designs, device modeling technology for nano CMOS with complic...
This paper presents a wearable electrophysiological interface with enhanced immunity to motion artifacts. Anti-artifact schemes, including a patch-type modular structure and real-time automatic level adjustment, are proposed and verified in two wireless system prototypes of a patch-type electrocardiogram (ECG) module and an electromyogram (EMG)-based robot-hand controller. Their common ExG read...
This paper presents a design of an UWB downconversion integrated CMOS resistive ring mixer with Linear Voltage Regulator (LVR), to supply required biasing voltages for the mixer section. The designed mixer circuit has been optimized for using in heart rate extraction system with microwave Doppler radar at 2.4GHz frequency. This mixer needs 2 DC bias voltages equal to 0.5 and 1 volts for its bes...
The fast development of wireless communication systems requires more flexible and cost effective radio architectures. A long term goal is the software defined radio, where communication standards are chosen by reconfiguration of hardware. Direct analog to digital conversion of the radio frequency (RF) signal is still unrealistic at present time, due to the high requirements imposed on the analo...
(ABSTRACT) The explosive growth in wireless communications has led to an increased demand for wireless products that are cheaper, smaller, and lower power. Recently there has been an increased interest in using CMOS, a traditional digital and low frequency analog IC technology, to implement RF components such as mixers, voltage controlled oscillators (VCOs), and low noise amplifiers (LNAs). Fut...
