A SINGLE-CHIP PREAMPLIFIER, which used lp, NMOS that has been designed for optical fiber PIN receivers, will be reported. The device, for many applications, could replace hybrid IC (HIC) preamplifiers.The transimpedance amplifier shown in Figure 1 is of the nonintegrating type discussed earlier". Transistors M 1 through M12 provide an A0 voltage gain. The feedback resistor, Rf, is obtained by biasing M20 in the linear (triode) region.
