Design and manufacturing process for high-voltage SiC MOSFETs have been developed in a 150mm CMOS fab. 1.2KV MOSFETs have been fabricated on this production line running in parallel with CMOS wafers. Typical devices have state-of-the-art performance with specific on-resistance of 4.5milliohm-cm2 and low leakage current up to 175°C junction temperature. The process manufacturability and quality of...
As technology scales down to nanometer regime the process variations have profound effect on circuit characteristics. Meeting timing and power constraints under such process variations in nano-CMOS circuit design is increasingly difficult. This causes a shifting from worst-case based analysis and optimization to statistical or probability based analysis and optimization at every level of circuit abstraction...
Due to exponential behavior of gate-oxide leakage current with temperature and technology scaling, leakage power plays important role in nano - CMOS circuit. In this paper, we present simultaneous scheduling and binding algorithm for optimizing leakage current during behavioral synthesis. It uses TED (Taylor Expansion Diagram) for generating optimized DFG (Data Flow Graph). Once DFG is obtained, it...
In this paper a high frequency low voltage low power tunable highly linear transconductor is presented. Shift level biasing is used at the inputs of both the amplifiers of a cross coupled differential pair for tuning. Bias currents of cross coupled differential amplifiers are adjusted to cancel third harmonic distortion. The proposed circuit is simulated in Cadence VIRTUOSO environment with UMC 0...
This paper presents design of an 8-bit 1.8 V segmented current steering (CS) digital-to-analog converter (DAC) using 0.18 mum double poly five metal CMOS technology. The DAC has been segmented as 6+2 to achieve optimum performance for minimum area. The simulation result shows a maximum DNL of 0.30 LSB and an INL of 0.33 LSB. The midcode glitch is 0.27 pV s. The simulated SNDR and SFDR of the segmented...
This paper presents an 8 bit 1.8 V 500 MSPS digital- to analog converter using 0.18mum double poly five metal CMOS technology for frequency domain applications. The proposed DAC is composed of four unit cell matrix. A novel decoding logic is used to remove the inter block code transition (IBT) glitch. The proposed DAC shows less number of switching for a monotonic input and the product of number of...
A fully differential CMOS sample and hold amplifier SHA) is described here.The circuit is designed as a front end sampler of a low-power, high-speed analog to digital converter. The SHA uses double-sampling technique to achieve high speed with reasonably low power consumption. Using 0.18oc CMOS technology, a resolution of 9 bit has been achieved at a sampling rate of 400 MHz. Also, to acquire superior...
In this paper, the effects of electrical heating in a silicon MEMS piezoresistive pressure sensor have been analyzed analytically and verified experimentally with a view to design energy efficient sensor node network where the sensors are operated for a prolonged time. For the integration of the MEMS sensor with the CMOS circuits, a SPICE compatible thermal equivalent circuit has been developed for...
A novel technique to implement static and dynamic translinear circuits based on CMOS CCII translinear (TL) loops is proposed. Various examples of static translinear circuits, such as squaring, square-root, geometric-mean circuits, are introduced. Falling into the category of dynamic translinear circuits, a second-order low-pass filter and a fourth-order filter offering high-pass, low-pass and band-pass...
