4. Design a 4 bit D/A converter using an op-amp summing amplifier (see Figure 8.3). Input voltages of 0 V and 5 V will be used to provide logical low and high inputs, respectively. V1 will be the most significant bit, V2 the next most significant bit, etc. Select the values of Rf and R1, R2 , R3, and R4 to provide an output that will vary from 0 V to - 5 V as the digital input varies from 0000 to 1111. Show the schematic diagram for this circuit.

2. a) Design a 9v DC oscillator circuit that produces a frequency of 500 Hz. The circuit may use a 555 timer or two transistor design(s). Show all calculations including the DC currents and bias voltages. Include the schematic and the required frequency formula(s). b) As a bonus, if a larger load were required to be connected to the chip, how would the schematic look and what components would be used to do design it? Also, as a theoretical approximation, if the 9v battery had a rating of 4 amp-hours, how long would it last powering this circuit? Show calculations to illustrate how you arrived at the answer.

Without writing or drawing tools to lean on, you must use words, not equations, graphs or schematics in your explanation. The current in a differential pair of transistors swings between the two sides of the transistor pair as the input voltage swings between the inputs. The output voltages of course follow the current inversely. Is this swing of current related to one of the chief advantages of differential operation, the elimination of common mode signals? Keep in mind, there is a restricted range of allowed current (and voltage) swing to keep the amplifier operating in a linear way
