ABSTRACT:
BACKGROUND
Processing of electronic signals has been traditionally accomplished in the voltage domain. In the voltage domain, the input and outputs of a circuit operate in the voltage mode and in general respond the voltage values of an applied input signal. However, there lies a need in electronic circuits to provide a design having higher operational speeds and lower power consumption. Circuits that are optimized to respond to voltage signals can be limited in optimization of higher speed and lower power consumption. Thus, there lies a need for circuits that operate in a current mode being optimized to be responsive to current values of an electrical signal rather than to voltage values in order to attain better operating characteristics in certain circuit designs. In a typical peak detector circuit, the circuit is designed to be responsive to a peak voltage value of an input signal. The circuit provides an output voltage representative of the peak value of the input circuit. Peak detector circuits are used, for example, in demodulation of amplitude-modulated (AM) or frequency-modulated (FM) signals. However, there lies a need to provide a circuit that is capable of being responsive to the peak current value of an input signal to realize a higher-speed, lower power current-mode peak detector.
