3 Signal Processing There’s a big, big world out there--both application space and viable technology Digital Signal Processing (DSP) Analog Signal Processing Apps: Geo-(ULF); Bio-(LF); Voice; AM; FM… Need Analog-to-Digital Conversion (ADC); basically solve the signal processing digitally (I.e. mainstream CMOS) Apps: Base-band-->multi-GigaHz Determined by combination of application requirements and technology capabilities R. Dutton, B. Murmann 5 Low-voltage Medium-voltage High-voltage RF OE ( CMOS ) ( CMOS +, BJT) ( CMOS ++, BJT+) (Si, III-V…”other”) (BJT voltage limits) (Silicon/MOS limits--freq., photons etc.) EE 114 (HO #4) Technology Comparison Parameter CMOS Si BJT SiGe BJT •W hy use CMOS for analog integrated circuits? Device Speed High High High Noise Poor Good Good Transconductance Poor Good Good Intrinsic gain Poor Better Best R. Dutton, B. Murmann 6 – Low cost, driven by high volume digital ICs – Integration with high density digital circuits • BiCMOS tends to be expensive EE 114 (HO #4)

4 Historic Comment + Prospective View Historic Comment : Bipolar Technology is COOL and has evolved dramatically using both Si-mainstream (I.e. SiGe BiCMOS) and with compound materials (I.e. InP etc.). (the new) EE214 will include consideration of these trends. You can also (if you are interested) look at the notes from EE215 (no longer offered eeclass stanford edu/spr08/ee215 offered, eeclass.stanford.edu/spr08/ee215 ) Prospective View : CMOS is the “circuit building material of choice” in the information age. Hence, this class will focus exclusively on CMOS circuits.
