Abstract :
A new binary-phase-shift-keying (BPSK) modulator is presented. It consists of a voltage control current source (VCCS), an LC resonator and a comparator and is named a switch-resonator BPSK modulator. This type of modulator is simpler than the traditional architectures. The experimental results are also reported; the bit rate and carrier frequency are 2.5 Mbit/s and 5 MHz, respectively
