Abstract
A low-voltage differential amplifier (10) includes a circuit (12) having a differential pair (14) and loads (22 and 24). The first load (22) can include a first embedded differential amplifier (30) and an output transistor (32) and the second load (24) can include a second embedded differential amplifier (36) and an output transistor (38). The differential amplifier (10) can provide a wide-voltage operable range. The differential amplifier (10) is particularly useful in connection with low-voltage temperature compensated crystal oscillators.
