Abstract :
A new compensation method for serial tuned optical receivers with overall current shunt feedback is described. At the cost of only one extra tuning inductor, a stable receiver has been obtained with a flat frequency response and improved noise performance, without the necessity of an equalisation circuit. A low-cost heterodyne receiver (300-900 MHz) has been realised with 4 dB noise reduction, using standard packaged components.
