Abstract
Two voltage mode digital modulators have been proposed i.e. Binary Amplitude Shift Keying (BASK) modulator and Binary Phase Shift Keying (BPSK) modulator. Both circuits use Dual-X Second Generation Current Conveyor (DXCCII) as the active building block and have the advantages of proper input impedances and use of grounded resistor. Detailed mathematical analysis of both circuits are given. The circuits have been simulated with SPICE using 0.35µm CMOS technology parameters. The supply voltage of ±1.8 V is used. Much satisfactory results have been obtained with the proposed circuits.
