Latest Patents

Uhanov holds a patent for a "Band-gap reference circuit with chopping circuit." This BGR circuit is designed for sub-1V integrated circuits and utilizes a voltage chopping circuit and/or a current chopping circuit along with a low-frequency filter. The circuit stabilizes the output reference voltage generated by an operational amplifier, a current mirror circuit, a CTAT stage, a PTAT stage, and an output stage. The voltage chopping circuit effectively reduces input offset and 1/f noise by periodically alternating the negative and positive temperature-dependent voltages supplied to the op-amp's input terminals. Additionally, the current chopping circuit minimizes variations caused by process-related differences in current mirror devices. The filter maintains loop stability and removes low-frequency noise generated by the chopping operations.
