Abstract: A radar detector (800) includes a radar transmitting device (110), a radar receiving device (120), an analog-to-digital converter (ADC) (130), and a digital processing unit (140). The radar transmitting device (110) transmits a first wireless signal. The radar receiving device (120) receives a second wireless signal to generate an analog reference signal (ASr) in response to the first wireless signal subdued from being transmitted, and receives a third wireless signal to generate an analog main signal (ASp) in response to the first wireless signal not subdued from being transmitted. The ADC (130) generates a digital reference signal (Sr) according to the analog reference signal (ASr), and generates a digital main signal (Sp) according to the analog main signal (ASp). The digital processing unit (140) adjusts the digital or analog main signal (Sp, ASp) according to the digital reference signal (Sr).

Abstract: A temperature detector (1) is used to detect a temperature of a circuit under test, and includes a temperature coefficient component (10), a multiplier (12), an impedance component (Zl) and a node (N1). The temperature coefficient component (10) is arranged in proximity to the circuit under test. A control terminal of the multiplier (12) is coupled to the temperature coefficient component (10). The impedance component (Zl) is coupled between the second terminal of the temperature coefficient component (10) and the control terminal of the multiplier (12), or between a second terminal of the multiplier (12) and a third voltage terminal. The node (N1) is formed between the temperature coefficient component (10) and the multiplier (12). An amplified detection current (Ia) flowing to a first terminal of the multiplier (12) is positively correlated to the temperature of the circuit under test.

Abstract: The frequency detector (100) includes a first impedance circuit (110) and a second impedance circuit (120). The first impedance circuit (110) has a first terminal for receiving an input signal (SIG IN ), and a second terminal for outputting a divisional signal (SIG DVS ). The second impedance circuit (120) has a first terminal coupled to the second terminal of the first impedance circuit (110), and a second terminal coupled to a first system voltage terminal (NV1). The frequency response of the first impedance circuit (110) is different from a frequency response of the second impedance circuit (120). The resistance of the first impedance circuit (110), a resistance of the second impedance circuit (120), and the divisional signal (SIG DVS ) change with a frequency of the input signal (SIG IN ).

Abstract: A power detector (10, 10B) has a signal input terminal (Pin), N limiting amplifiers (30A, 30B, 30C, 30D), N rectifiers (40A, 40B, 40C, 40D) and a signal output end. N is an integer greater than 1. The signal input terminal receives an input signal (Si), and the signal output end outputs a detection signal (VPD). The N limiting amplifiers generate N amplified signals (Vop1, Vop2, Vop3, Vop4) according to N attenuated signals (Vinp1, Vinp2, Vinp3, Vinp4) having different attenuation. Each rectifier (40A, 40B, 40C, 40D) receives a corresponding amplified signal and outputs a rectified signal. The detection signal (VPD) is associated with the sum of N rectified signals (Io1, Io2, Io3, Io4) outputted from the N rectifiers (40A, 40B, 40C, 40D), and all transistors of the power detector (10, 10B) are bipolar junction transistors.
