摘要：

An MOS cascode current source that employs both active and passive series feedback is reported in this letter. Small-signal analysis and SPICE simulation results show that a CMOS implementation of the active-feedback cascode current source provides an output open-circuit Thevinin voltage greater than 106 V. This represents an increase of about two orders of magnitude as compared with the conventional cascode current source. The active-feedback cascode current source also maintains the same output voltage swing range as the conventional double cascode. © 1990 IEEE
