5. CMOS Operational Amplifiers - IMS
ims.unipv.it5. CMOS Operational Amplifiers 7 Analog Design for CMOS VLSI Systems Franco Maloberti Power supply rejection ratio: If a small signal is applied in series with the positive (or negative) power supply, it is transferred to the output with a given gain Aps+ (or Aps-). The ratios between differential gain and power supply gains furnish the two PSRRs.

Class E Amplifiers - NorCal QRP
norcalqrp.org• Class E saves ~ 50% on TX DC input power to PA – Low drive power (17 mW vs. 0.6w) saves additional power • Class C requires large TO220 PA transistors • Class E needs only tiny T092/SOT23 300mw/600mw packages • $0.14 for a new pair of Class E QRP finals! • Low wasted TX pwr (Heat) – For 5w output, 0.5 to 1w heat (class E) vs. 5 ...
SECTION 5: OPTICAL AMPLIFIERS
uweb.engr.arizona.edufiber amplifiers (EDFAs) due to their ability to amplify signals at the low loss 1.55 m wavelength range. Characteristics of EDFAs (advantages): High power transfer efficiency from pump to signal power (> 50%). Wide spectral band amplification with relative flat gain (>20 dB) – useful for WDM applications. Saturation output > 1 mW (10 to 25 dBm).

OPERATIONAL AMPLIFIERS: Basic Circuits and Applications
people.engr.tamu.eduThe transconductance amplifiers is typically used in closed loop for switched-capacitor circuits. The transconductance amplifiers are often used in open loop for continuous-time filters. (Gm-C filters) •Where do you use transconductance amplifier (VCIS) or current amplifier (ICIS) amplifiers? —In continuous-time current-mode filters.
