摘要：

We present a high-frequency fully-differential current-mode buffer to interface off-chip currents with no significant degradation of the frequency response, and to measure current-mode ICs using standard equipment. It has been fabricated in a 0.8 mu m double-poly double-metal CMOS technology and features more than 37 MHz bandwidth. In order to show its functionality, this unit has been incorporated to the front end of a switched-current bandpass Sigma Delta modulator featuring a 9 bit dynamic range at 10 MHz clock frequency for a 30 kHz signal bandwidth centred at 2.5 MHz.
