Abstract :
This paper presents the Binary Phase Shift Keying (BPSK) modulator for high data rate medical imaging for capsule endoscope. The BPSK modulator consists of a mixer and a ring oscillator. The ring oscillator provides carrier frequency of 433MHz and mix with the mixer to produce BPSK modulated signal. The modulator is designed using Silterra 0.13μm CMOS process. For supply voltage of 1.2 V, data rate of 3.5Mbps the mixer has power consumption of 1.2mW and at output power of -10.7 dBm.
