The goal of this project is to implement a 10-bit segmented current steering TSMC 0.25µm CMOS digital to analog converter. Binary coded 10-bit data was input to the converter. The converter will convert all combinations of ten bits from digital form into correspondent " staircase " voltage levels. A low pass filter placed after the output terminal of the… (More)
A phase lock loop is a closed-loop system that causes one system to track with another. More precisely, a PLL can be perceived as a circuit synchronizing an output signal with a reference or input signal in frequency as well as phase. High-performance phase lock loops are widely used within a digital system for clock generation, timing recovery, and to… (More)
This paper presents the design and implementation of a 6 Gbps clock and data recovery (CDR) system for Serial Advanced Technology Attachment (SATA) standard. The CDR incorporates half rate phase detector and is realized using a 2 loop PLL consisting of a coarse loop and a fine loop. Fast frequency acquisition is acquired through coarse loop and fine phase… (More)
State of art phase locked loop (PLL) design methodologies and techniques are always of many mixed-signal circuit designers' interests. In this paper, a fully differential PLL having good common-mode noise rejection (low phase noise) has been designed and demonstrated using TSMC 0.25µm CMOS technology. The design and demonstration included a dead zone… (More)
This paper presents the design of a first-order continuous-time sigma-delta modulator. It can accept input signal bandwidth of 10 kHz with oversampling ratio of 250. The modulator operates at 1.8 V supply voltage and uses 0.18 um CMOS technology. It achieves a level of 60 dB SNR..
This paper presents the design of low power, low cost design of temperature sensor that has been designed keeping in view VLSI circuits and technology changes. The circuit occupies an area close to 0.01mm 2 , which is less than 1/100 th of the area occupied by most of the previous circuits that use capacitors and A/D converters. Power dissipation of the… (More)
This paper describes an 8-bit, 10 MSamples/second analog to digital converter, with 2V fully differential input range, which is implemented in TSMC 0.25µm CMOS technology. It achieves low power dissipation of 25mW, and the chip area is 0.56mm 2. Measured performance yields a very good VTC curve and a sine wave fitting curve for 200KHz input at 10Msample/s,… (More)
This paper presents the design of a low input (0.75 to 1.75V) and low power dissipation pipelined CMOS ADC. The 8 bits ADC consumes 78.3mW power at 2.5V supply voltage. The DNL and INL are 0.6LSB and 0.7LSB respectively, and SFDR is 51.259dB at 195kHz input frequency. The chip area is 1.023 mm × 0.795 mm with TSMC025..m CMOS technology.
