Abstract
A reset signal is generated by a TIA circuit alone. In an embodiment, a transimpedance amplifier configured to convert a current signal into a voltage signal includes a transimpedance stage including an amplification stage constituted of a transistor with a grounded emitter, and a comparator configured to compare a collector voltage of the transistor with a reference voltage and output a reset signal.
