Design in Optoelectronic Oscillator Integrated on Vibration Sensor of GPS Drone

The proposed paper includes matching Giber folded mixer, local oscillator, analog to digital converter (ADC) and Gm-C bandpass IF filter. A switched capacitor (SC) filter by using bilinear transformation to a 5
^th
–order elliptic low pass ladder filter is presented for optoelectronic oscillator integrated. This article presents a continuous-time low pass sigma-delta analog-to-digital converter on vibration sensor of GPS Drone with a chain of integrators and with weighted capacitive feedforward summation (CICFF) topology which is a desirable solution for implementation in low power applications. The summation of feedforward signals is implemented by weighted capacitors, without the necessity of any additional active components as add feedback after quantized.
