I specialized in precision analog circuitry design and layout for rotational vibration sensing along with power supply design and layout. Projects included: ● Saving the company $8M with subtle layout changes that enabled using lower cost amplifiers. ● Simultaneously reducing cost and improving efficiency and performance by carefully designing a linear regulator replacement for a specialized power circuit using statistical techniques. ● Using laser doppler vibrometry to prove beyond a doubt a correlation between observed failures and piezoelectric dielectric capacitors.
