Short summary
This paper demonstrates a squaring circuit, which is a key element in many low-power receivers, designed in a low-cost technology. For its functionality, the circuit exploits the typical characteristics of a transistor. To enhance the speed of the circuit and consequently to enable higher data rates for the receiver, a novel “boosting circuit” is implemented. An additional control circuit regulates the output and simplifies the detection of an incoming signal.
