-# Proficiencies
+I have a strong appreciation for sensing systems and exploring the
+More-Than-More scaling for CMOS technology. The idea here is to augment
+traditional fabrication techniques for sensing bio-markers, particles, light
+and all kinds signals using electronics. More generally however I study analogue
+signal processing techniques in the context of all-digital systems. My main
+research interests currently are time-domain processing and asynchronous custom
+digital logic for high performance applications such as ultra-low-power medical
+devices and ultra-wide-band radio transceivers. In these systems we can encode
+information using the relative timing of clock edges e.g. pulse-width-modulation
+to do analogue processing using digital logic which leads to a new approach to
+realizing certain functions and implementations.

+representation of information. For example in time-domain systems we can realize
+resolve units of time with almost arbirtary precision, very often down to a
+KT/C equivilent limit. Howver some-how similar to traditional analog systems,
+where the maximum dynamic range is limited by the voltage-supply, in
+time-domain systems this limit comes from rate at which we can make
+observations. For example say we have a 1 MHz pulse-width-encoded signal then
+we can only resolve relative timing information at 1 MHz. We could increase
+our dynamic range by reducing the pulse-repetition-rate but our information
+rate stays constant since we only double the information-per-pulse but half
+its rate. Comparing this again to traditional analog with a simple RC circuit
+where our maximum dynamic is set by the supply voltage to KT/C ratio and this
+is fixed irrespective of the resistor or bandwidth of the circuit. Again we can
+show that this is a fundamental consequence of the
+[equi-partition-theorum](https://www.wikipedia.org/equipartition-theorum)
+irrespective of how we represent/encode information.
 
-## Programming languages
+The main advantage of time-domain processing is that we can exhaustively use
+digital logic. This is not only highly-adventagious when designing in a
+deep sub-nanometer technology since they are geared towards these kind of
+circuits but also we dont suffer from performance losses due to device parameter
+degredation in the same way a tranditional op-amp might. In fact you can show
+that time-domain circuits can realize almost ideal operators for summation,
+integration, multiplication, and thier inverses through closed-loop operation.
