Generalized autoregressive conditional heteroscedasticity model (henceforth GARCH model) is a successful model for modeling and forecasting the volatility of financial market. But GARCH models use the closing price data of trading days to calculate the return on assets, without considering the asset price changes during the trading day. Especially when asset prices change greatly during the trading...
In this paper, we present a VHF and UHF bands oscillator which mainly composed of a Bi- CMOS active load differential amplifier (Diff. amp). We use H-spice and ADS to verify that the active load differential amplifier oscillator output frequency is 817.1 MHz at 3.3 volts power supply under CIC 0.35 um-GeSi process. We also use discrete devices on bread board to prove the circuit is an oscillator circuit...
In this paper, we present a VHF (Very High Frequency) band oscillator which mainly composed of a BJT active load differential amplifier (Diff. amp). We use H-spice to verify that the active load differential amplifier oscillator output frequency is 900 MHz at 2.0 volts power supply under CIC 0.18 um-Si process. We also use discrete devices on bread board to prove the circuit is an oscillator circuit...
