This work introduces key simulation techniques enabling
the design of a 16b 65MSps pipeline ADC in 0 . 4 ~ ~
45GHz-jr SiGe BiCMOS. A complete methodology for INL
investigation with SPICE leads to understand the distortion
introduced by Track/Hold as well as quantizer at 3.3V
supply and high input range (4Vpp). Simulations of aperture
uncertainty are presented that match the measured 230fs
jitter, yielding 74.5dBFS SNR at 150MHz input. The test
chip delivers 78.3dBFS SNR, 88dBc SFDR at
65MSpdlMHz with 97OmW power consumption.
