Title Proper : TEMPERATURE COMPENSATED BIASING SCHEMES FOR BIPOLAR OP AMPS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Two temperature compensated current mirrors were analyzed and simulated. Thetemperature compensated cascode current mirror showed about 1 variation of outputcurrent over the temperature range of -50پ‍-C to 150پ‍-C. The main contribution of thisthesis was the development of the Widlar compensated current mirror. Simulationsshowed that the output current varied about 0.25 over the temperature range of -50پ‍-C to1 50پ‍-C.The two temperature compensated current mirrors were used in the biasingscheme of the 741 op amp. The use of these current mirrors significantly reduced thetemperature variation of the biasing currents in the op amp. The temperature variation ofthe slew rate and the input bias currents was found to be reduced while that of the openloop gain and the -3dB.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
