Amplifiers with single-pole frequency responses used in their "roll-off" regions. Class of crystal oscillators based on use of negative-voltage-gain amplifiers at frequencies well into "roll-off" frequency regions of their gain-versus-frequency curves. Defining characteristic helps keep costs of oscillators low; not necessary to use more expensive amplifiers that have flat frequency responses out to desired operating frequencies. Enables amplifier to produce phase shift necessary for oscillation, reducing cost further by eliminating need for some of passive components in oscillators of more conventional design.
