WORK EXPERIENCE

Ganesan Designs 07/93 – Present

Since 1993, involved in defining, designing and marketing audio, video, radio multimedia, power supervisors, disk-drive, datacom, telecom, etc. products

Used CMOS, Bipolar and BiCMOS technologies

Clients include Texas Instruments, Intel, Motorola, Tanner Research, Samsung, GEC Plessey, etc.

The last contract worked on was a power management chip for solid state drives

oInvolved an hysterectic control architecture

oHad all the power transistors integrated and used a copper pillar RDL technology and had an EEPROM chip on chip in addition

oThe chip supports 4 buck regulators and one boost regulator and a whole bunch of programmable functions like start up, in rush current, etc.

oThe most difficult aspects of the design were:

Keeping the high voltage transients acceptable

Keeping the sleep mode current low

Fast response to transient load changes

Meeting the cross regulation requirements which turned out to be a bear

oChip is going though its 3rd iteration now; being made in Dongbu's BiCMOS

Prior to this, worked on a USB current limited switch

Prior to that, worked on a novel CSA (current sense amplifier architecture)

oThis involved sensing millivolts of differential voltages in the presence of +20 to -4 v of common mode voltages and some nasty terminal conditions for enterprise systems, etc.

Prior to that, worked on a ramp less Class D amplifier

Prior to that, worked on a fly-back adapter for a power supply for a drill

Prior to that, worked on high-capacitive drive opamp

Prior to that, worked on a technology scalable 10-bit pipe lined A/D converter
