MASTERS THESIS

Design of a wireless cardiogram system for acute and long term health care monitoring

A wireless system to monitor patients’ Electrocardiogram and Phonocardiogram has been developed.

The ECG and Phonocardiogram acquired from the patient are sent to a remote computer for monitoring.

The main tasks in the Thesis are

o Designed analog signal processing circuitry to process ECG and PCG signals acquired from the

patient.

o Developed embedded C programs for the Wireless SoC to perform analog to digital conversion

of the signals, wireless transmission of the data and data reception at the remote unit

o Designed PCB layouts and build prototype and tested them.

o Developed a GUI in LabVIEW for patient monitoring at the remote location

PROJECTS

A 2.4 GHZ Wireless Local Area Network (WLAN) Transceiver Design using Agilent ADS

Heterodyne receiver and Direct Conversion Transmitter were simulated in reference with the standard

802.11b. Agilent ADS software was used for the simulation with realistic components obtained from

2

specification sheets from different vendors. SNR, BER, IP3, NF and receiver sensitivity have been

calculated and compared with the standards specified in the IEEE 802.11b

Design of power amplifier using Agilent ADS

A power amplifier has been simulated using Agilent ADS. Performed DC and load line analysis, stability

analysis, load pull analysis and determined input and output matching circuits.

Design of a low power 2.4 GHz Low Noise Amplifier using Cadence

Designed, layout and tested a low power 2.4GHz Double Poly Bipolar (DPBP) LNA using a 0.35 µm

TSMC process. Behavioral analysis was done in MATLAB and transistor level simulation was done

using Cadence SpectreRF. Layout was done using Cadence Virtuoso Layout Editor.

Design of a Ring Oscillator circuit in Mentor Graphics IC Studio

A ring oscillator circuit was designed and simulated using Mentor graphics IC studio. The layout has

been drawn and verified using design rule check (DRC) and layout vs schematic (LVS) tools. Parasitic

capacitance and resistance extraction and post layout simulation has also been performed.

Simulation of a two stage CMOS Op amp with an output buffer using WINSPICE

Determined the open loop gain, operating point, common mode rejection ratio, power supply rejection

ratio and output voltage range of a two stage op amp using the Winspice program.

Fabrication of PMOS Transistors on a silicon wafer in the microelectronics laboratory

Performed thin film processes like oxidation, photo lithography, sputtering, etching, film coating etc on a

silicon wafer to fabricate PMOS transistors in a class 100 clean room. Finally, the devices have been

characterized using a curve tracer.
