Abstract: This paper describes an on-chip analog bus whose bandwidth is limited primarily by an off-chip amplifier. It uses only a digital 3-state inverter for each bus input. The high-speed and constant low-input capacitance of this scheme make it suitable for measuring sensitive or even digital signals. For equal silicon area, the signal bandwidth is demonstrated to be 10 to 40 times that of previously reported transmission gate schemes.
