PROJECTS

•Design of a 90-Ohm differential line for high speed data transfer across a motherboard

Width and spacing for a loosely coupled differential line and tightly coupled differential line were obtained using the Rogers tool. Minimum width and spacing was maintained at 3 mils. The results were verified with the transmission line simulator Maxwell 2D. The p.u.l. L and C matrices were extracted and the field plots for even/odd mode excitations were plotted. A simulation setup was generated, and the eye diagrams were calculated based on the differential lines designed. Lossless lines with a length of 50 cm and pseudo-random-bit-stream (PRBS) data at 10 Gbps were assumed. A termination scheme for best signal integrity was suggested. Mismatched lengths were created to check for skew while maintaining a 50% eye height.

•Design of CMOS operational transconductance amplifier (OTA) with consideration of performance, chip area and temperature variations

Designed an OTA circuit to attain minimum differential voltage gain of 30 V/V and minimum bandwidth of 30 MHz with operational temperature range: 0ºC to 85ºC, along with the design for the layout using techniques such as common centroid, dummy device, shared source-drain and perform DRC and LVS checks.

•Design of a 2-stage differential-to-single-ended amplifier using TSMC 300nm technology

Designed a 2-stage differential-to-single-ended amplifier with the ability to drive 10pF capacitive load with minimum overall voltage gain of 250 V/V and bandwidth of 30 MHz

•Design of various types of Common Source amplifier with consideration of layout parasitic effect on gain-bandwidth using TSMC 300nm transistors

Designed circuit and layout for passive load, diode-connected load and current source load common-source amplifiers with minimum gain of 15.

•TSMC 300nm modeling IV extraction, long-short channel and temperature effect

Run DC analysis to obtain the drain current-drain voltage curves and drain current-VGS curve of the (W/L=10, using minimal length allowed by the TSMC 300nm technology) NMOS and PMOS in saturation region at 0ºC, 25ºC and 85ºC.
