Problem 4      Version 2024a Given the following BJT circuit with values as indicated, answer the questions below.  Choose best matching answer, you can reuse matching answers Make sure to show your work and answers on work paper, including the answer with units, and put a box around the final answers. Assume active mode operation, with VBE=0.7V. Given RB2=RB1= 120kohms   Vcc = 3V   Rc = 1kohms   RE = 1kohms Beta = 100 It is operating at a temperature of 290K so assume VT = 0.025 for this problem

Problem 3      Version 2b Given the integrated amplifier below, with parameters as listed, answer the following questions. Choose best matching answer, you can reuse matching answers Make sure to show your work and answers on work paper, including the answer with units, and put a box around the final answers. VDD = 5V, L = 1um, W1(for Q1) = 1um, Q2 is twice the width of Q1 k’p = 1mA/V^2, k’n = 4mA/V^2, W3 (for Q3) = 8um IREF = 2mA, Vtn = |Vtp| = 1V lambda = 0.1 for NMOS, lambda = 0.5 for PMOS  

Problem 1      Version 2a For this op amp circuit with V1 = 2V,  R1 = 1kohms,  R2 = 4kohms,  RL = 4kohms   Choose best matching answer, you can reuse matching answers Make sure to show your work and answers on work paper, including the answer with units, and put a box around the final answers.

True/False: Neurons function by sending and receiving chemical messages.

Which of the below is NOT given as a reason we dream?

The limbic system includes all of the following except:

True/False: Critical thinking involves not blindly accepting arguments and conclusions. It examines assumptions, assesses the source, uncovers hidden values, weights evidence, and assesses conclusions.

The best definition of a double-blind procedure is: 

In one sentence, describe the difference between a theory and a hypothesis.
