On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation
(Institute of Electrical and Electronics Engineers Inc., 2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers
is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation
equivalent to an ...
Noise-cancellation-based nonuniformity correction algorithm for infrared focal-plane arrays
(OPTICAL SOC AMER, 2008)
Updating dynamic noise models with moving magnetoencephalographic (MEG) systems
(Institute of Electrical and Electronics Engineers Inc., 2019)
Optically pumped magnetometers have opened many possibilities for the study of human brain function using wearable moveable technology. In order to fully exploit this capability, a stable low-field environment at the sensors ...
Fully-differential offset-cancelling circuit with configurable output common-mode voltage
(IEEE, 2013)
For certain applications, the offset voltage of the amplifiers represents a problem that must be addressed, since it may affect the transfer characteristics of the system. Offset memorization techniques allow to partially ...

Self-Interference Cancelation Through Advanced Sampling
(Institute of Electrical and Electronics Engineers, 2018-04)
Self-interference is the main obstacle to overcome in order to enable a wireless device to simultaneously transmit and receive in overlapped frequency bands. There is much interest to suppress this interference employing ...
