• An emitter-coupled pair with a dynamic bias current and a source-coupled pair with a dynamic bias corrent are proposed as an exponential-law element and a square-law element that operate as a floating bipolar junction transistor (BJT) and a floating MOS field-effect transistor (MOSFET). In bipolar technology, a hyperbolic sine function circuit and a hyperbolic cosine function circuit are easily obtained by subtracting and summing the output currents of two symmetrical exponential-law elements with positive and negative input signals. In the same manner, an operational transconductance amplifier (OTA) and a squaring circuit are obtained by subtracting and summing the output currents of two symmetrical square-law elements with positive and negative input signals in CMOS technology. The proposed OTA and squaring circuit possess the widest input voltage range ever reported.
