Title: Phase-shifter circuit and fm detector circuit
Inventor: SAEKI TAKAO
IPC: H03H11/18
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To realize phase shift with stable delay time in a simple circuit. SOLUTION: Transistors 12a and 12b are turned on and off by input signals in mutually opposite phases. By turning on the transistors 12a and 12b, capacitors 12a and 12b are discharged. By turning off the transistors 12a and 12b, the capacitors 16a and 16b are charged with a constant current from constant current generators 18a and 18b. Then, a voltage increasing gradually during the term of L of the input signal can be obtained at each positive input terminal of comparators 14a and 14b. The voltage is compared with each given voltage of reference power supplies 20a and 20b so that a signal with a rise timing shifted 90 deg. is obtained as an output from the comparators 14a and 14b. The outputs of comparators 14a and 14a are shifted with each other 180 deg..  When an RS flip-flop 22 is reset at the rise time, a signal with a 90 deg. phase delay to the input signal is obtained as the output.
