I. General Presentation of the circuit (give circuit name)

Explain briefly the principle of the circuit. Don’t exceed one page.

II. Functional description

1. Schematic of the circuit (give circuit name)

Complete block diagram of the circuit

Show the internal links between the internal blocks of the circuit

Figure 1. Detailed schematic of the circuit (give circuit name)

2. Description of the different function (give circuit name)

Brief description of the different functions of the circuit. In particular, detail the analog blocks that you will design.

III. Circuit pin-out

1. Proposed pin-out

Show all the external I/O pads of the circuits and precise their properties (power supply, ground reference, analog/digital input …). The names of I/O pads must be the same than those given in the block diagram (II.1).

Precise the nature of the circuit package (justify according to pin number, thermal consideration, size)

2. List of I/O

Table with the name, a brief description and the nature of I/O (e.g. analog/digital input, output, bidirectional I/O, power, ground, output drain …

3. Power supplies

List of the different power supplies (pairs Vdd/Gnd) Give the nominal power supply voltage

4. Constraints for I/O connection

Give indication about the external circuitry connected to each I/O.

Precise the nature of required external components (active, passive devices, power supply …)

It is possible to show a typical schematic of the circuit.

If possible, indicate the values of circuit parameter or precise that they will be set by simulation Detail ESD protection strategy to fulfill ESD design rules.

IV. Detailed specifications of the circuit (give circuit name)

1. Customer specifications

Remind the list of electrical and environmental specifications of the customer succinctly.

2. Description of specifications

Describe each specification: explain in several sentences what is expected and if possible give one or several figures which describe the ideal result that you should obtain in simulation (see the example below).

Example: illustration of the constraints about the output voltage vs. power supply voltage.

Figure 2. Maximum evolution of the output reference voltage vs. power supply voltage

V. Detailed schematic of the designed analog functions
