Problem 3 A receiver has a bandwidth of 1 MHz and a noise figure of 10 dB. The receiver sensitivity is -90 dBm. The Boltzmann constant is k=1.38x10-23 Joule/deg K, and the room temperature is 300 deg Kelvin. a) What is the ratio of the SNR at the input to the receiver (computed over the bandwidth of interest) to the SNR at the output of the receiver? b) What is the noise power at output of the receiver? c) Find...

Question # B.5 (a) In a communication system, suppose the associated operating temperature is doubled. Then, what is the corresponding change in the system capacity (C), if the signal power-level at the input is kept constant? Is C a linear function of temperature? Justify (b) A mixer-stage in a radio receiver has a NF 20 dB and this mixer-stage is preceded by a preamplifier with a NF - 9 dB. The available power-gain ratio of the amplifier is equal to...

3 1. Photodiode amplifier circuit You are designinga CF photosensor circuit for a light detection and ranging LiDAR) system in autonomous vehicles. The circuit utilizes a transimpedance amplifier to convert low-level RF photodiode current signal to a usable voltage output. It consists of a photodiode, an amplifier, and feedback capacitor/resistor pair as shown in Figure 1. We will derive simple equations to...
