Time difference amplifiers are used in fluorescence experiments where the input
time differences are in picoseconds. The key challenge is to provide the linearity of
such amplifiers with sufficient gain over the required input range. This amplifier
has a gain greater than 2ps/ps, with the input ranging from 10 pS to 1000 pS. The
gain error is found to be less than 10% at a temperature of 25◦C , voltage range
of 800mV to 1.2 V. The overall power consumption from simulation is 4 mW.
This design uses differential signalling based architecture and is an open loop
system to realize these
specifications. Initially results of the design were verified
using simulation techniques and then the physical implementation was done resulting
in an integrated circuit that was fabricated and tested.
